GENERAL DESCRIPTION

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 m V,

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.
