AD8417-2

The AD8417-2 is a high voltage, high resolution, and dual channel current sense amplifier. It features an initial gain of 60 V/V, with a maximum ±0.3% gain error over the entire temperature range. The AD8417-2 performs bidirectional current measurements across a shunt resistor in a variety of 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 channel density, without compromising performance.
