AD8417BRMZ-RL

双向，零漂移，电流检测放大器 Bidirectional, Zero Drift, Current Sense Amplifier

**GENERAL DESCRIPTION**

The AD8417 is a high voltage, high resolution current shunt amplifier. It features an initial 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 AD8417 offers excellent input common-mode rejection from −2 V to +70 V. The AD8417 performs bidirectional current measurements across a shunt resistor in a variety of

automotive and industrial applications, including motor control, power management, and solenoid control.
