INA199A3RSWR Description

Short technical summary and product information.

The Texas Instruments INA199A3RSWR is a versatile current-sense amplifier designed for applications requiring precise current monitoring. It supports both low-side and high-side sensing with a wide common-mode voltage range from -0.3 V to 26 V, independent of the supply voltage.

 

This device offers a maximum accuracy of ±1.5% and operates within a temperature range of -40°C to 125°C. It is available with fixed gains of 50 V/V, 100 V/V, and 200 V/V, enabling sensing of small shunt voltage drops as low as 10 mV full-scale. The INA199A3RSWR draws a low quiescent current of 100 µA (maximum).

 

Packaged in a compact 10-UQFN (1.8x1.4) surface-mount package, the INA199A3RSWR is suitable for space-constrained designs. Its features make it ideal for overcurrent protection, system optimization through precise current measurement, and closed-loop feedback circuits.
