INA271AQDRQ1 Description

Short technical summary and product information.

The INA271AQDRQ1 from Texas Instruments is an automotive-qualified current-sense amplifier with a voltage output. It is designed to accurately measure voltage drops across current shunts at common-mode voltages ranging from -16V to +80V, independent of the supply voltage.

 

This device features a gain error of ±1% maximum and an offset voltage of ±2.5mV maximum, ensuring precise measurements. It offers a gain option of 20 V/V and a bandwidth of up to 130 kHz, making it suitable for current-control loops. The amplifier operates from a supply voltage of 2.7V to 18V and has a low quiescent current of 900µA maximum.

 

The INA271AQDRQ1 is housed in an 8-pin SOIC package, suitable for surface mounting. Its pinout is optimized for external filtering, simplifying circuit design. This amplifier is AEC-Q100 qualified, making it ideal for demanding automotive applications.

 

Key specifications include an operating temperature range of -40°C to 125°C. The device is designed for high-side current sensing, providing flexibility in system design.
