Analog Devices Inc. AD8215YRZ-RL

Description
The AD8215 is a high voltage, precision current shunt monitor with a set gain of 20 V/V and a maximum ±0.3% gain error over the entire temperature range. It features a buffered output voltage that directly interfaces with any typical converter. The AD8215 has an excellent common-mode rejection from -2 V to 65 V, independent of the 5 V supply. It performs unidirectional current measurements across a shunt resistor in various industrial and automotive applications, such as motor controls, solenoid controls, or battery management. Special circuitry ensures output linearity throughout the input differential voltage range of 0 mV to 250 mV, regardless of the common-mode voltage present. The AD8215 operates over a temperature range of -40°C to 125°C and is available in a small 8-lead SOIC N package.
