Analog Devices Inc. AD8417 Bidirectional Current Sense Amplifiers
Analog Devices Inc. AD8417 Bidirectional Current Sense Amplifiers feature a 60V/V initial gain and a maximum ±0.3% gain error across the entire temperature range (-40°C to +150°C). The Analog Devices Inc. AD8417 amplifiers' buffered output voltage interfaces seamlessly with typical converters. With excellent input common-mode rejection from -2V to +70V, the devices are ideal for bidirectional current measurements in automotive and industrial applications like motor control, power management, and solenoid control. The AD8417WH variant maintains breakthrough performance even in extreme temperatures, featuring a zero-drift core for a typical offset drift of 0.1µV/°C.
