Digital potentiometers

6 August 2014 Analogue, Mixed Signal, LSI

Microchip has expanded its 36 V digital potentiometer portfolio with two new volatile, I²C devices: the MCP45HV31 and MCP45HV51. They offer a 5 k resistance, 10 V to 36 V analog operation and 1,8 V to 5,5 V digital operation, for systems requiring wide signal swings or high supply voltages. The devices support both 7- and 8-bit resistor configurations, and a high terminal/wiper current, including the ability to sink/source up to 25 mA on all terminal pins for driving larger loads. These features, combined with an extended temperature range of -40°C to


+125°C, make them well suited for high-voltage and high-temperature applications such as in the industrial, automotive and audio markets.
