AMC3306M25DWER

AMC3306M25DWER is a Texas Instruments reinforced isolated delta-sigma modulator with an integrated isolated DC/DC converter, in a 16-pin SO-MOD package on a 2000-unit reel — for shunt-based current sensing in motor drives, solar inverters and onboard chargers: ±250 mV linear input range, single 3.3 V or 5 V low-side supply, reinforced isolation rated 6000 VPEAK per VDE V 0884-11 and 4250 VRMS for one minute per UL 1577, over -40°C to +125°C. The ±250 mV range is the selection point: it accepts the larger shunt drop of higher-current phases without saturating, with offset error of ±50 µV maximum, gain error of ±0.2% maximum, 81 dB SNR and 75 kV/µs minimum common-mode transient immunity beside SiC and GaN edges. Business impact: the integrated DC/DC powers the high side from the controller side, cutting an isolated supply per channel and shortening safety-layout work. Selection advice: pick the M25 code when the shunt drop approaches ±250 mV; if the signal is only tens of millivolts and offset drift is the binding spec, the AMC3306M05DWER offers ±0.4 µV/°C maximum drift instead of this code's ±1 µV/°C — match the full code, as the input range is fixed by the M05/M25 letters.
