Description
The INA240-Q1 device is an automotive-qualified,voltage-output, current-sense amplifier with enhanced
PWM rejection that can sense drops across shuntresistors over a wide common-mode voltage range from
–4 V to 80 V, independent of the supplyvoltage. The negative common-mode voltage allowsthe device to
operate below ground, accommodatingthe flyback period of typical solenoid applications.Enhanced PWM
rejection provides high levelsof suppression for large common-mode transients(ΔV/Δt) in systems that
use pulse width modulation(PWM) signals (such as motor drives and solenoidcontrol systems). This
feature allows for accuratecurrent measurements without large transients andassociated recovery ripple
on the output voltage.
This device operates from a single 2.7-V to 5.5-Vpower supply, drawing a maximum of 2.4 mA of supply
current. Four fixed gains are available: 20V/V, 50 V/V, 100 V/V, and 200 V/V. The low offsetof the zero-drift
architecture enables current sensingwith maximum drops across the shunt as low as 10-mV full-scale.
Grade 1 versions are specified overthe extended operating temperature range (–40°C to+125°C) and are
offered in an 8-pin TSSOP and 8-pinSOIC packages. Grade 0 versions are specified overthe extended
operating temperature range (–40°C to+150°C) and are offered in an 8-pin SOIC package.
