INA240A2PWR Ultra-Precise Current Amplifier Description
The INA240A is a voltage-output current-sense amplifier with improved PWM rejection that can detect voltage drops across shunt resistors over a wide common-mode voltage range of –4 V to 80 V, regardless of the supply voltage. The device can operate below ground due to the negative common-mode voltage, which accommodates the flyback period of typical solenoid applications. In systems that use pulse width modulation (PWM) signals, enhanced PWM rejection provides high levels of suppression for large common-mode transients (V/t) (such as motor drives and solenoid control systems). This feature enables precise current measurements without large transients and associated output voltage recovery ripple.
This device draws a maximum of 2.4 mA of supply current from a single 2.7-V to 5.5-V power supply. There are four fixed gains: 20 V/V, 50 V/V, 100 V/V, and 200 V/V. The zero-drift architecture's low offset allows current sensing with maximum shunt drops as low as 10-mV full-scale. All versions have an extended operating temperature range of –40°C to +125°C and are available in an 8-pin TSSOP and an 8-pin SOIC package.
