INA240A3QPWRQ1 Description

Short technical summary and product information.

The Texas Instruments INA240A3QPWRQ1 is an automotive-qualified current sense amplifier designed for precise current monitoring in demanding applications. It operates over a wide common-mode voltage range from -4 V to 80 V, independent of the supply voltage, and offers enhanced Pulse Width Modulation (PWM) rejection for improved signal integrity in noisy environments.

 

This amplifier provides a voltage output proportional to the current sensed across a shunt resistor. Key electrical specifications include a gain of 100 V/V, a maximum gain error of 0.20%, and a maximum offset voltage of ±25 µV. It boasts excellent DC CMRR of 132 dB and AC CMRR of 93 dB at 50 kHz, ensuring accurate measurements even with significant common-mode noise.

 

The INA240A3QPWRQ1 is housed in a compact 8-pin TSSOP (PW) package, suitable for surface-mount designs. It operates within an ambient temperature range of -40°C to 125°C, making it robust for automotive and industrial applications. The device is AEC-Q100 qualified, signifying its suitability for automotive environments.
