Description
AI
The AD8215 is a high voltage, precision current shunt monitor. It features a set gain of 20 V/V, with a maximum ±0.3% 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 AD8215 performs unidirectional current measurements across a shunt resistor in a variety of industrial and automotive applications, such as motor controls, solenoid controls, 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 AD8215 has an operating temperature range of −40°C to +125°C and is offered in a small 8-lead SOIC_N package.ApplicationsHigh-side current sensingMotor controlsTransmission controlsEngine managementSuspension controlsVehicle dynamic controlsDC-to-dc convertersQualified for Automotive
