ANALOG DEVICES AD8418AWBRMZ Current Sense Amplifier, High Side, Low Side, 250 kHz, MSOP, 8 Pins, -40 °C, 125 °C

AD8418A is a bidirectional, zero drift, current sense amplifier. It is a high voltage, high resolution current shunt amplifier. It 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. This amplifier performs bidirectional current measurements across a shunt resistor in a variety of automotive and industrial applications, including motor control, power management, and solenoid control, low-side current sensing, diagnostic protection etc. It includes EMI filters and patented circuitry to enable output accuracy with pulse-width modulation (PWM) type input common-mode voltages.
