GENERAL DESCRIPTION
The AD8213 is a dual-channel, precision current sense amplifier. It features a set gain of 20 V/V, with a maximum ±0.5% 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 AD8213 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.
