AD8211 High Voltage, Current Shunt Monitor

Applications High-side current sensing Motor controls Transmission controls Engine management Suspension controls Vehicle dynamic controls DC-to-dc converters

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 common-mode 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.

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 AD8211 has an operating temperature range of −40°C to +125°C and is offered in a small 5-lead SOT package.
