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.
The AD8417 offers breakthrough performance throughout the
−40°C to +125°C temperature range. It features a zero drift core,
which leads to a typical offset drift of 0.1 µV/°C throughout the
operating temperature range and the common-mode voltage
range. The AD8417 is qualified for automotive applications. The
device includes EMI filters and patented circuitry to enable
output accuracy with pulse-width modulation (PWM) type
input common-mode voltages. The typical input offset voltage
is ±200 µV. The AD8417 is offered in 8-lead MSOP and SOIC
packages.
