INA225AIDGKR Description

Short technical summary and product information.

The INA225AIDGKR from Texas Instruments is a versatile current-sense amplifier with analog output. It is designed to accurately measure current by sensing the voltage drop across a shunt resistor, supporting common-mode voltages ranging from 0V to 36V, independent of the supply voltage. This device features four pin-selectable gain settings, allowing for flexibility in measurement ranges: 25 V/V, 50 V/V, 100 V/V, and 200 V/V.

 

Key electrical characteristics include a low input offset voltage of ±150µV maximum across all gains and a low input offset voltage drift of 0.1 µV/°C typical. The amplifier offers a bandwidth of up to 250 kHz at a gain of 25 V/V and a low quiescent current of 0.35 mA maximum. The gain error is specified at ±0.15% for lower gains and up to ±0.3% for the highest gain, with a gain drift of 10 ppm/°C.

 

Packaged in an 8-VSSOP or 8-MSOP, the INA225AIDGKR is suitable for surface-mount applications. Its operating temperature range is -40°C to 125°C, making it robust for various environmental conditions. The device is capable of bidirectional current sensing and can be used in low-side configurations.
