Analog Devices Inc. AD8213 Precision Current Sense Amplifiers
Analog Devices AD8213 Precision Current Sense Amplifiers provide a 20 V/V set to gain with a maximum ±0.5% gain error over the entire temperature range. AD821’s buffered output voltage interfaces directly with any standard converter. The devices’ excellent −2V to +65V common-mode rejection is independent of the 5V supply. The AD8213 amplifiers perform unidirectional current measurements across a shunt resistor in a wide range of industrial and automotive applications. These applications include motor control, solenoid control, and battery management.
