AD8211WYRJZ-R7
电流灵敏放大器 High Voltage Current Shunt Amp High Voltage, Current Shunt Monitor
GENERAL DESCRIPTION AD8211WYRJZ-R7
The AD8211 is a high voltage, precision current shunt amplifier. It features a set gain of 20 V/V, with a typical ±0.35% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. Excellent commonmode rejection from −2 V to +65 V is independent of the 5 V supply. The AD8211 performs unidirectional current measurements across a shunt resistor in a variety of industrial and automotive applications, such as motor control, solenoid control, or battery management.
