Description

The INA240 device is a 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. All 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.
