AMC3306M05DWER

AMC3306M05DWER is a Texas Instruments reinforced isolated delta-sigma modulator with an integrated isolated DC/DC converter, in a 16-pin SO-MOD package — for shunt-based current sensing in motor drives, solar inverters and EV chargers: ±50 mV linear input range, single 3.3 V or 5 V supply on the low side, and a reinforced barrier rated 6000 VPEAK per VDE V 0884-11 and 4250 VRMS for one minute per UL 1577, over -40°C to +125°C. The ±50 mV range is the selection point: paired with a small shunt it converts a tiny drop into resolution, with offset error of ±50 µV maximum, offset drift of ±0.4 µV/°C maximum, gain error of ±0.2% maximum and 75 kV/µs minimum common-mode transient immunity keeping the bitstream clean at fast switching edges. Business impact: the integrated DC/DC removes the separate isolated high-side supply, so each current channel needs fewer parts and less creepage-critical layout. Selection advice: choose the M05 code when the shunt signal is tens of millivolts and the tighter ±0.4 µV/°C drift matters; for shunt drops approaching ±250 mV the AMC3306M25DWER in the same package is the wide-range sibling — the two are not interchangeable once the shunt is sized.
