INA193AIDBVR

INA193AIDBVR is the tape-and-reel SOT-23-5 ordering code for the Texas Instruments INA193 current-shunt monitor, listed as ACTIVE on the TI buy page for this exact code. Its gain is fixed at 20 V/V - the INA194 (50 V/V) and INA195 (100 V/V) are different devices, and every figure here is the INA193 row of the shared datasheet. It measures across a common-mode range of -16 V to +80 V with CMR of 80 dB minimum and 94 dB typical, input offset of ±0.5 mV typical and ±2 mV maximum referred to input, gain error of ±0.2% typical and ±1% maximum, from a 2.7 V to 18 V supply with quiescent current of 900 µA maximum, over -40 °C to +125 °C. The selection point is high-side current sensing that keeps working through load dumps and inductive transients far above the supply rail: battery packs, automotive and industrial bus monitoring. Selection advice: size the shunt for the offset error at the lowest current you must resolve - at 20 V/V the ±2 mV maximum offset, not the gain error, usually dominates the low-end reading. Parameters verified against the TI INA193 datasheet SBOS307 (electrical characteristics for the INA193 gain option).
