The Texas Instruments INA240A3PWR is a voltage-output, current-sense amplifier designed for sensing voltage drops across shunt resistors. It features an impressive common-mode voltage range from -4 V to 80 V, independent of the supply voltage, allowing operation below ground for applications like solenoid flyback periods.
Key electrical specifications include a maximum gain error of 0.20% and a gain drift of 2.5 ppm/°C. The offset voltage is a maximum of ±25 µV with an offset drift of 250 nV/°C. This specific variant, INA240A3, offers a gain of 100 V/V. It also boasts excellent common-mode rejection ratios, with 132 dB DC CMRR and 93 dB AC CMRR at 50 kHz, providing high suppression for common-mode transients.
The device operates within an ambient temperature range of -40°C to 125°C. It is housed in a 8-pin TSSOP (PW) package and is suitable for surface mount applications. The standard package quantity is 2000 units on tape and reel.
This current sense amplifier is ideal for applications requiring precise current monitoring in systems with high voltage swings or significant PWM switching, such as motor control, power management, and battery charging systems.
