The AD8418AWBRZ is a high voltage high resolution Current Shunt Amplifier features an initial gain of 20V/V, with a maximum ±0.2% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. The AD8418A offers excellent input common-mode rejection from -2 to +70V. The AD8418A offers breakthrough performance throughout the -40 to +150°C temperature range. It features a zero drift core, which leads to a typical offset drift of 0.1µV/°C throughout the operating temperature range and the common-mode voltage range. The AD8418A 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 ±200µV.
