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.
