MAX485ESA+

MAX13487EESA+ is an Analog Devices (Maxim) half-duplex RS-485/RS-422 transceiver with automatic direction control in 8-pin SO — for industrial fieldbus without direction-control firmware: Modbus nodes and building automation. The auto-direction control is the selection point: the transceiver switches itself, freeing an MCU pin and simplifying code versus the MAX485. Selection advice: the ESA+ denotes 8-pin SOIC — pick the MAX13487E when firmware simplicity matters; for the lowest cost, the plain MAX485 is cheaper but needs manual direction control. Terminate the bus at both ends per RS-485 practice. Parameters verified against the ADI official datasheet ordering table.

AD620BRZ-R7 is an Analog Devices instrumentation amplifier in 8-lead SOIC_N, 7-inch tape and reel — gain set from 1 to 10,000 with a single external resistor, ±2.3 V to ±18 V dual supply (4.6 V to 36 V single), 15 µV maximum input offset (B grade), 1 MHz bandwidth, 1.3 mA maximum supply current, rated −40 °C to +85 °C. The single-resistor gain setting is the selection point: bridge sensors, thermocouples and strain gauges get a precision differential front end with one resistor instead of a matched-resistor op-amp network that drifts with temperature and layout. Selection advice: BRZ is the B grade (tighter offset than the A-grade AD620ARZ-R7), R-8 the SOIC package, R7 the 7-inch reel — the AD620BRZ-RL is the identical die on a 13-inch reel if your line prefers larger reels. DigiKey lists this code Active. Evidence: the ADI AD620 datasheet Rev. H ordering guide confirms the ordering code, B grade, 7-inch reel and −40 to +85 °C rating.

AD8066ARZ is an Analog Devices dual 145 MHz FastFET operational amplifier in 8-lead SOIC, tube packing — 180 V/µs slew rate, 7 nV/√Hz voltage noise, 1 pA-class FET input bias current, 5 V to 24 V supply, rail-to-rail output, -40 °C to +85 °C. The FastFET input stage is the selection point: photodiode preamps and high-impedance sensor front ends get wideband speed without the noise penalty of bipolar inputs. Selection advice: ARZ is the SOIC-8 tube code — AD8066ARZ-R7 is the reel twin, and the single-channel AD8065 covers single-op-amp designs. Honest availability note: Mouser currently flags this code as restricted availability, so confirm the lot before committing to production volumes. Evidence: the ADI AD8066 official datasheet confirms the bandwidth, slew rate and package codes, and Mouser confirms the exact ordering code.

ADA4077-2ARZ is an Analog Devices dual precision operational amplifier in 8-lead SOIC, tube packing — 15 µV typical input offset (50 µV max A-grade), 0.25 µV/°C drift, 3.6 MHz gain-bandwidth, 1.2 V/µs slew rate, 1 nA input bias and 400 µA per channel, specified over −40 °C to +125 °C on 5 V to 30 V supplies (±2.5 V to ±15 V). Unity-gain stable with no phase reversal and stable into 1000 pF capacitive loads. The offset-plus-drift combination is the selection point: thermocouple, RTD and strain-gauge front ends hold calibration across temperature without trimming, which is the whole value proposition of a precision op amp. Selection advice: the ARZ code is the tube version — ARZ-R7/ARZ-RL is the same die on tape and reel for pick-and-place; this is not a rail-to-rail output part, so size your signal swing inside the ±15 V rails. For single-channel or quad layouts use the ADA4077-1/ADA4077-4. Evidence: LCSC and element14/Newark listings confirm 15 µV, 3.6 MHz, −40 to +125 °C, SOIC-8 and wide distributor stock.

ADUM4121-1ARIZ is an Analog Devices single-channel isolated gate driver — 8-lead wide-body SOIC, 2 A peak output, internal Miller clamp, 5 kV rms isolation, CMTI over 150 kV/µs, 2.5–6.5 V input / 4.5–35 V output. The 150 kV/µs CMTI is the selection point: immunity to the fastest SiC switching transients — the driver that stays quiet when the bridge slams. Selection advice: ADI lists the ADUM4121-1ARIZ as Production. The -1ARIZ code pins the 8-lead wide-body variant — match it to your footprint; the 6-lead ADUM4120 family is a different package. Verify the 4.5–35 V output range covers your gate drive voltage, and the 2 A peak against your switch gate charge. Evidence: ADI data confirms Production, 8-lead wide-body SOIC, 2 A peak, Miller clamp, 5 kV rms isolation, 150 kV/µs CMTI. Match the full ADUM4121-1ARIZ code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADUM4121-1BRIZ is an Analog Devices single-channel isolated gate driver — 8-lead wide-body SOIC with internal Miller clamp, 2 A output with thermal shutdown, 5 kV rms isolation, −40 to +125 °C. The 8-lead package with Miller clamp is the selection point: more pins for separate source/sense connections plus Miller protection — the ADUM4121 step up from the 6-lead ADUM4120. Selection advice: ADI lists the ADUM4121-1BRIZ as Production. The -1BRIZ code pins the 8-lead wide-body variant — match it to your footprint; the 6-lead ADUM4120 family is a different package. For Kelvin source connections verify the pinout against your layout. Evidence: ADI data confirms Production, 8-lead wide-body SOIC, Miller clamp, 2 A, 5 kV rms isolation. Match the full ADUM4121-1BRIZ code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADUM4121ARIZ is an Analog Devices single-channel isolated gate driver — 8-lead wide-body SOIC with internal Miller clamp, 2 A output with thermal shutdown, 5 kV rms isolation, −40 to +125 °C. The Miller clamp in the 8-lead package is the selection point: separate source/sense pins plus Miller protection — the ARIZ variant for layouts where the -1BRIZ pinout does not fit. Selection advice: ADI lists the ADUM4121ARIZ as Production. The ARIZ code pins the 8-lead wide-body variant with Miller clamp — match it to your footprint; the 6-lead ADUM4120 family is a different package. Verify the 2 A drive against your switch gate charge at the switching frequency. Evidence: ADI data confirms Production, 8-lead wide-body SOIC, Miller clamp, 2 A, 5 kV rms isolation. Match the full ADUM4121ARIZ code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADUM4121BRIZ is an Analog Devices single-channel iCoupler isolated gate driver in 8-lead wide-body SOIC, tape-and-reel packing (RIZ) — 2 A peak output (2.3 A at 12 V / 4 Ω gate resistance), 5000 VRMS isolation per UL 1577, >150 kV/us common-mode transient immunity, maximum 53 ns isolator-plus-driver propagation delay, −40 to +125 °C. The internal Miller clamp and dual supplies are the selection point: 2.5–6.5 V input (UVLO at 2.5 V) speaks directly to low-voltage controllers, while the 4.5–35 V output rail drives IGBT/MOSFET gates with true galvanic isolation — the integrated clamp shunts Miller-induced gate charge on the falling edge to defeat parasitic turn-on in half-bridge layouts. Selection advice: this is the B grade — its VDD2 UVLO is ~7.3 V typical, suited to 12 V gate-drive rails; grade A (~4.4 V) and grade C (~11.3 V) serve lower or higher rails, so pick the grade matching your actual gate-drive voltage rather than substituting by habit. It is not a drop-in for the dual-channel ADUM4122 family members. Analog Devices lists ADUM4121BRIZ as Production. Evidence: ADI ADuM4121 datasheet (including the −1/−EP variants) and distributor listings confirm 2 A, internal Miller clamp, 5000 VRMS, >150 kV/us CMTI, wide-body 8-SOIC and tape-and-reel packing. Match the full ADUM4121BRIZ code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADUM4122ARIZ is an Analog Devices single-gate isolated driver — 8-lead wide-body SOIC with dual output pins for adjustable slew-rate control, 2 A output per pin, 3 A peak short-circuit current, 5 kV rms isolation, CMTI over 150 kV/µs. The dual output pins are the selection point: split the gate resistor across two pins to tune slew rate and damp ringing — EMI control built into the driver footprint. Selection advice: ADI lists the ADUM4122ARIZ as Production (recommended for new designs). The ARIZ code pins the 8-lead wide-body variant — match it to your footprint; the dual-pin output needs both pins routed, unlike single-output drivers. Verify the 150 kV/µs CMTI against your fastest switching edge. Evidence: ADI data confirms Production/RND, 8-lead wide-body SOIC, dual output pins, 2 A per pin, 5 kV rms isolation. Match the full ADUM4122ARIZ code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

DS1307ZN+ is an Analog Devices (Maxim) 64x8 serial I2C real-time clock with 56 bytes of NV SRAM in narrow SOIC-8 — for basic timekeeping in SMT designs: appliances, simple controllers and data loggers. The tiny SOIC-8 with battery-backed SRAM is the selection point: timekeeping plus configuration storage in minimal board space. Selection advice: the ZN+ denotes narrow SOIC-8 — pick it for SMT production; the DIP-8 DS1307+ suits hand assembly. For accuracy without calibration, the DS3231's integrated TCXO is the step up. External 32.768 kHz crystal required. ADI lists this part as PRODUCTION. Parameters verified against the ADI official product page.
