AMC3330DWER

AMC3330DWER is a Texas Instruments precision reinforced isolated amplifier with an integrated isolated DC/DC converter, in a 16-pin SO-MOD (DWE) package on a 2000-unit reel — for isolated voltage sensing in motor drives, solar inverters and power equipment: ±1 V input range, fixed gain of 2.0, single-supply operation, 1200 VRMS working voltage, reinforced isolation rated 6000 VPK reinforced and 4250 VRMS per UL 1577, over -40°C to +125°C. The ±1 V input at gain 2.0 is the selection point: a divider scaled to ±1 V fills the input range and the gain of two lifts the signal with margin, holding offset error to ±0.3 mV maximum, offset drift to ±4 µV/°C maximum, gain error to ±0.2% maximum, nonlinearity to ±0.02% maximum and common-mode transient immunity to 85 kV/µs minimum. Business impact: the integrated DC/DC removes the separate isolated supply per measurement channel, reducing BOM count and creepage-critical routing in safety designs. Selection advice: choose this code when the sense divider is scaled around ±1 V; the AMC3311DWER in the same DWE package family instead takes a 2 V high-impedance input at gain 1.0 — the input range and gain are fixed per code, so confirm the divider ratio before quoting. Parameters verified against the TI AMC3330 datasheet.
