INA240A2DR Description

Short technical summary and product information.

The Texas Instruments INA240A2DR is a highly precise, bidirectional current sense amplifier designed for accurate current measurements. It features enhanced Pulse Width Modulation (PWM) rejection, making it suitable for applications with noisy power rails.

 

This amplifier supports a wide common-mode voltage range from -4V to 80V, independent of the supply voltage. Key electrical specifications include a maximum input offset voltage of ±25 µV and a gain error of 0.20% maximum. Available gains include 20 V/V, 50 V/V, 100 V/V, and 200 V/V, catering to various current sensing needs.

 

The INA240A2DR operates within an ambient temperature range of -40°C to 125°C. It is available in TSSOP (PW) 8 and SOIC (D) 8 package types, supporting surface mount applications. The device's low quiescent current of 2.6 mA maximum contributes to power efficiency in designs.

 

This current sense amplifier is ideal for applications requiring precise current monitoring, such as motor control, power management, and battery charging systems. Its robust performance and wide operating range make it a versatile component for demanding electronic designs.
