AMC3311DWER

AMC3311DWER 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 EV charging: 2 V high-impedance input, fixed gain of 1.0, single 3.3 V or 5 V low-side supply, 1200 VRMS working voltage, reinforced isolation rated 6000 VPK per DIN EN IEC 60747-17 and 4250 VRMS per UL 1577, over -40°C to +125°C. The 2 V high-impedance input is the selection point: it suits resistive-divider bus sensing without loading the divider, with offset error of ±1 mV maximum, offset drift of ±10 µV/°C maximum, gain error of ±0.2% maximum, nonlinearity of ±0.02% maximum and 85 kV/µs minimum common-mode transient immunity per the datasheet. Business impact: the integrated DC/DC eliminates the external isolated supply, so a reinforced voltage channel fits one footprint. Selection advice: the DWER reel code is the only catalog ordering code for the AMC3311 — quote it in full. Against the AMC3330DWER on this site: 2 V at gain 1.0 here versus ±1 V at gain 2.0 there; size the divider to the code you choose. Parameters verified against the TI AMC3311 datasheet.
