Qualified for automotive applications The AD8418 is a high voltage, high resolution current shunt
amplifier. It features an initial gain of 20 V/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 V to +70 V. The AD8418 performs bidirectional
current measurements across a shunt resistor in a variety of
automotive and industrial applications, including motor
control, battery management, and soleno...
