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.

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.

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.
