INA180A3IDBVR

INA180A3IDBVR is the tape-and-reel SOT-23-5 ordering code for the Texas Instruments INA180 current-sense amplifier, listed by TI as Active / Production in the datasheet ordering appendix (SBOS741H). The A3 code is the 100 V/V gain variant, and every figure here is from the A3 column of the datasheet: bandwidth of 150 kHz typical at that gain with a 10 pF load, internal gain resistance of 5 kΩ, gain error of ±0.1 % typical and ±1 % maximum, input offset of ±25 µV typical and ±150 µV maximum at zero differential input (VIN+ = 0 V, 25 °C, 5 V supply), widening to ±100 µV typical and ±500 µV maximum at a 12 V input - the tighter pair does not hold across the whole common-mode window - common-mode rejection of 84 dB minimum and 100 dB typical, slew rate of 2 V/µs and quiescent current of 197 µA typical and 260 µA maximum at 25 °C (300 µA maximum over the full -40 °C to +125 °C range), over a 2.7 V to 5.5 V supply and a -0.2 V to +26 V common-mode range. The selection point is shunt-based current measurement where a 100 V/V gain lets a small, low-loss shunt resistor still fill the ADC input range: motor drives, battery management and power-rail monitoring get a clean measurement without a precision amplifier design effort. Selection advice: the INA180 family offers four gain options (A1 at 20 V/V, A2 at 50 V/V, this A3 at 100 V/V and A4 at 200 V/V) sharing one pinout, so the gain letter is the critical match point - a wrong-gain substitute reads back a proportionally wrong current, and the error is silent. Size the shunt for the A3 gain so full-scale current lands inside the output swing. Parameters verified against the TI INA180 datasheet SBOS741H, Table 9-1 gain variants and the A3 electrical column.
