GENERAL DESCRIPTION
The AD8417-2 is a high-voltage, high-resolution dual-channel current
shunt amplifier. It features an initial gain of 60 V/V and 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 AD8417-2 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 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 AD8417-2 is offered in a small 10-ball 1 mm × 1.9 mm WLCSP.
It requires a smaller board area than a typical single-channel
current sense amplifier, increasing 2× channel density, and a lower
cost per channel without compromising performance.
