Description

The MCP4011 devices are volatile, 6-bit (64 wiper steps) digital potentiometers that are programmed/reprogrammed through a simple up/down serial interface. The MCP4011 devices offer a variety of configurations simplifying design while minimizing cost, package size and pin count. The MCP4011 device offers a voltage divider (potentiometer), with all terminals available on pins. The MCP4012 is a true rheostat, with both nodes of the resistor available on pins. The MCP4013 device offers a voltage divider (potentiometer), with one terminal connected to ground. The MCP4014 device is a rheostat mode device, with one terminal of the resistor connected to ground. The MCP4011 devices are available with resistor values of 2.1K?, 5K?, 10K? and 50K?. These devices operate from a single 1.8V-5.5V supply and draw less than 1 A while operating in the static state.
