AD8418BRMZ

AD8418 is a high voltage, high resolution current shunt amplifier. This device performs bidirectional current measurements across a shunt resistor in a variety of automotive and industrial applications, including motor control, battery management, and solenoid control. It features an initial gain of 20V, with a maximum ±0.15% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. It is widely used in application such as high-side current sensing in motor controls, solenoid controls, power management, low-side current sensing, diagnostic protection etc.
