Product Description

The INA240A1PWR from Texas Instruments is a high and low side, bidirectional, zero-drift, current sense amplifier with enhanced PWM rejection in 8 pin TSSOP package. It can sense drops across shunt resistors over a wide common mode voltage range from -4V to 80V, independent of the supply voltage. The negative common mode voltage allows the device to operate below ground, accommodating the flyback period of typical solenoid applications. Enhanced PWM rejection provides high levels of suppression for large common mode transients (ΔV/Δt) in systems that use pulse width modulation (PWM) signals (such as motor drives and solenoid control systems). This feature allows for accurate current measurements without large transients and associated recovery ripple on the output voltage. It is used in pressure regulators and telecom equipment.
Operates from a single 2.7V to 5.5V
Enhanced PWM rejection
Excellent CMRR, -132dB DC CMRR, -93dB AC CMRR at 50KHz
Accuracy of 0.20% (max) gain error, 2.5ppm/°C (max) gain drift
Offset voltage of ±25µV (max), offset drift of 250nV/°C (max)
20V/V gains
Quiescent current of 2.4mA (max)
Operating temperature range from -40°C to 125°C
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
