INA199A1 Datasheet PDF – 26V, Current Sense Amplifier

Part Number: INA199A1

Marking : OBG

Function: Voltage Output, High or Low Side Measurement, Bi-Directional Zero-Drift Series

Package: SC70-6 Pin, UQFN 10 type

Manufacturer: Texas Instruments




The INA199A1 series of voltage output current shunt monitors can sense drops across shunts at common-mode voltages from –0.3V to 26V, independent of the supply voltage. Three fixed gains are available: 50V/V, 100V/V, and 200V/V. The low offset of the Zerø-Drift architecture enables current sensing with maximum drops across the shunt as low as 10mV full-scale.


1. Wide Common-Mode Range: –0.3 V to 26 V

2. Offset Voltage: ±150 μV (Maximum) (Enables Shunt Drops of 10-mV Full-Scale)

3. Quiescent Current: 100 μA (Maximum)
