AMC1311DWVR

AMC1311DWVR is the tape-and-reel SOIC-8 (DWV wide-body) ordering code for the Texas Instruments AMC1311 reinforced isolated amplifier — for isolated voltage sensing across a reinforced barrier: 2 V high-impedance input, fixed gain of 1, reinforced isolation rated 7000 VPK and 5000 VRMS per UL 1577, over -40°C to +125°C. This is the non-B code on its own datasheet rows: offset error of ±9.9 mV maximum, offset drift of ±20 µV/°C typical, gain error of ±1% maximum, gain drift of ±30 ppm/°C typical and nonlinearity of 0.04% maximum — a looser error table than the B grade, at the standard industrial temperature range. The selection point is cost-matched accuracy: where the measurement budget tolerates ±1% gain error, this code covers bus-voltage monitoring in drives, inverters and chargers without paying for B-grade precision. Selection advice: the temperature floor is the hard divider — this code starts at -40°C, and only the B grade (AMC1311BDWVR, also listed on this site) extends to -55°C with ±1.5 mV offset and ±0.2% gain error; do not quote one code against the other's error table. Parameters verified against the TI AMC1311 datasheet SBOS965 and the package option addendum.
