The AD8215 is a high voltage, precision current shunt monitor. Special circuitry is devoted to output linearity being maintained It features a set gain of 20 V/V, with a maximum ±0.3% gain throughout the input differential voltage range of 0 mV to 250 mV, error over the entire temperature range. The buffered output regardless of the common-mode voltage present. The AD8215 voltage directly interfaces with any typical converter. Excellent has an operating temperature range of −40°C to +125°C and is common-mode rejection from −2 V to +65 V is independent of offered in a small 8-lead SOIC package. 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.
