The Texas Instruments INA240A1 is an analog output current sense amplifier featuring bidirectional capability and enhanced Pulse Width Modulation (PWM) rejection. It is designed for automotive applications and offers an ultra-precise measurement with a wide common-mode voltage range from -4 V to 80 V.
Key electrical specifications include a maximum input offset voltage of ±25 µV and a maximum gain error of 0.20%. The amplifier provides multiple gain options, with the INA240A1 variant offering a voltage gain of 20 V/V. It boasts a high Common Mode Rejection Ratio (CMRR) of 132 dB (DC) and 93 dB (AC at 50 kHz), along with a bandwidth of 400 kHz.
Available in TSSOP and SOIC packages, the INA240A1 is suitable for surface mount applications. Its operating temperature range spans from -40°C to +150°C, making it robust for demanding environments. The device is AEC-Q100 qualified for automotive use.
This current sense amplifier is ideal for applications requiring accurate current monitoring in the presence of high switching noise, such as motor control, power management, and battery monitoring systems.
