Description

General part information

INA240-Q1 Series

The INA240 -Q1 device is an automotive-qualified, voltage-output, current-sense amplifier with enhanced PWM rejection that can sense drops across shunt resistors over a wide common-mode voltage range from –4 V to 80 V, 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.

This device operates from a single 2.7-V to 5.5-V power supply, drawing a maximum of 2.4 mA of supply current. Four fixed gains are available: 20 V/V, 50 V/V, 100 V/V, and 200 V/V. The low offset of the zero-drift architecture enables current sensing with maximum drops across the shunt as low as 10-mV full-scale. Grade 1 versions are specified over the extended operating temperature range (–40°C to +125°C) and are offered in an 8-pin TSSOP and 8-pin SOIC packages. Grade 0 versions are specified over the extended operating temperature range (–40°C to +150°C) and are offered in an 8-pin SOIC package.
