INA225AQDGKRQ1 Description

Short technical summary and product information.

The INA225AQDGKRQ1 from Texas Instruments is a voltage-output, current-sense amplifier. It is designed to sense voltage drops across current-sensing resistors at common-mode voltages ranging from 0 V to 36 V, independent of the supply voltage.

 

This device offers four pin-selectable gain levels: 25 V/V, 50 V/V, 100 V/V, and 200 V/V. It features a low-offset, zero-drift architecture with precision gain values, enabling current sensing with maximum drops across the shunt as low as 10 mV of full-scale while maintaining high accuracy.

 

The INA225AQDGKRQ1 is AEC-Q100 qualified and operates within a temperature range of -40°C to 125°C. It is supplied in an 8-pin VSSOP package suitable for surface mounting.

 

Key electrical characteristics include a wide common-mode range of 0 V to 36 V, a maximum offset voltage of ±150 µV, and a quiescent current of 350 µA maximum. The bandwidth is 250 kHz at a gain of 25 V/V.
