Microchip MCP6C02 zero-drift, 65V high-side current sense amplifier

The MCP6C02 is a single high-side current sense amplifier designed specifically to sense the current through a shunt resistor and convert this measurement to a proportional output voltage.

The input pins can support voltages up to 65V. The output voltage range will be determined by a separate supply pin, which spans 2V to 5.5V to make it easy to interface to an ADC or MCU that is operating at 2.5V, 3.3V and 5V.
