Motor controls Transmission controls Engine management Suspension controls Vehicle dynamic controls DC-to-dc converters GENERAL DESCRIPTION The AD8211 is a high voltage, precision current shunt amplifier. It Special circuitry is devoted to output linearity being maintained features a set gain of 20 V/V, with a typical 0.35% gain error throughout the input differential voltage range of 0 mV to 250 mV, over the entire temperature range. The buffered output voltage regardless of the common-mode voltage present. The AD8211 directly interfaces with any typical converter. Excellent common- has an operating temperature range of 40C to +125C and is mode rejection from 2 V to +65 V is independent of the 5 V offered in a small 5-lead SOT package. 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.
