AD8215: High Voltage, Current Shunt Monitor

The AD8215 is a high voltage, precision current shunt monitor. It features a set gain of 20 V/V, with a maximum ¡À0.3% 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¡ãC to +125¡ãC and is offered in a small 8-lead SOIC_N package.
