The AD8213 is a dual-channel, precision current sense amplifier. It features a set gain of 20 V/V, with a maximum ±0.5% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. Excellent common-mode rejection from −2 V to +65 V, is independent of the 5 V supply. The AD8213 performs unidirectional current measurements across a shunt resistor in a variety of industrial and automotive applications, such as motor control, solenoid control, or battery management.Special circuitry is devoted to output linearity being maintained throughout the input differential voltage range of 0 mV to 250 mV, regardless of the common-mode voltage present. The AD8213 also features additional pins that allow the user to low-pass filter the input signal before amplifying, via an external capacitor to ground. The AD8213 has an operating temperature range of −40°C to +125°C for the Y grade, −40°C to +150°C for the H grade and is offered in a small 10-lead MSOP package.ApplicationsHigh-side current sensingMotor controlsTransmission controlsDiesel injection controlsEngine managementSuspension controlsVehicle dynamic controlsDC to DC converters
