Microchip Technology MCP40D17, MCP40D18, & MCP40D19 Digital POT ICs

Microchip Technology MCP40D17, MCP40D18, and MCP40D19 Single Digital Potentiometers are are volatile, 7-bit (128 wiper steps) digital POT ICs with an I2C-compatible interface. These devices are offered in 5kΩ, 10kΩ, 50kΩ, and 100kΩ end-to-end resistance values, and are available in miniature 5-lead and 6-lead SC-70 packaging. The MCP40D17, MCP40D18, and MCP40D19 Digital Potentiometers are ideal for use in a variety of applications, including PC servers, amplifier gains control and offset adjustment, sensor calibration, set point or offset trimming, RF amplifier biasing, and more.
