Product Overview
The INA212 is a Texas Instruments current-shunt monitor amplifier in the Signal_Chain category. The INA212 variant has a fixed gain of 1000 V/V and is specified for current-sense signal conditioning where small shunt voltages are amplified for measurement.
Operating conditions include a 2.7 V to 26 V supply range and a recommended 5 V nominal operating supply. The recommended common-mode input voltage is 12 V nominal, with common-mode input ranges of -0.3 V to 26 V for Version A and -0.1 V to 26 V for Versions B and C across -40°C to +125°C.
Electrical performance includes ±0.55 µV typical offset voltage, 0.1 µV/°C typical offset drift, 105 dB minimum and 140 dB typical CMRR for INA212, ±0.02% typical gain error, and 3 ppm/°C typical gain drift. Package options are SC70-6 at 2.00 mm × 1.25 mm and Thin UQFN-10 at 1.80 mm × 1.40 mm, with RθJA values of 227.3°C/W and 107.3°C/W respectively.
