The AD8219 is a high voltage, high resolution, current shunt amplifier. It features a set gain of 60 V/V, with a maximum ±0.3% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. The AD8219 offers excellent input common-mode rejection from 4 V to 80 V. The AD8219 performs unidirectional current measurements across a shunt resistor in a variety of industrial and telecom applications including motor control, power management, and base station power amplifier bias control.
