Product Overview
The INA214 is a Texas Instruments current-shunt monitor amplifier in the Signal_Chain category. It has a fixed 100 V/V gain and implements the output relationship VOUT = (ILOAD x RSHUNT) x Gain + VREF, allowing the REF pin to set the output reference level within a 0 V to V+ input range.
Electrical operation is specified for a 2.7 V to 26 V supply range, with common-mode input voltage support from -0.3 V to 26 V for Version A and -0.1 V to 26 V for Versions B and C over -40°C to +125°C. The device lists ±1 µV typical input offset voltage, 0.1 µV/°C typical offset drift, 3 ppm/°C typical gain drift, and 30 kHz bandwidth for INA214 with CLOAD = 10 pF.
Package options include SC70 (6) at 2.00 mm x 1.25 mm and UQFN (10) at 1.80 mm x 1.40 mm. Thermal resistance is 227.3°C/W for the DCK SC70 6-pin package and 107.3°C/W for the RSW UQFN 10-pin package, supporting package selection during board-level thermal review.
