Microchip – MCP45HV31 and MCP45HV51: 5kΩ Digital Potentiometers with 36V Operating Voltage

The MCP45HV31/51 are the industry’s first digipots to offer a 5kΩ resistance with a specified operating voltage of 36V. They provide 10V to 36V analog operation and 1.8V to 5.5V digital operation, for systems requiring wide signal swings or high power supply voltages. The MCP45HV31/51 digipots support both 7-bit and 8-bit resistor configurations, and a high terminal/wiper current, including the ability to sink/source up to 25mA on all terminal pins for driving larger loads.
