AD8418WBRMZ (ANALOG DEVICES)

The AD8418WBRMZ is a high voltage high resolution Current Shunt Amplifier features an initial gain of 20V/V, with a maximum ±0.15% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. The AD8418 offers excellent input common-mode rejection from -2 to +70V. The AD8418 offers breakthrough performance throughout the -40 to +125°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 AD8418 is fully qualified for automotive applications and 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.
