MCP4014 - Microchip Technology

MCP4014 (MCP4011 - MCP4014) Low-Cost 64-Step Volatile Digital POT

The MCP4011/2/3/4 devices are volatile, 6-bit Digital Potentiometers that can be configured as either a potentiometer or rheostat. The wiper setting is controlled through a simple Up/Down (U/D) serial interface. CS U/D 2-Wire Interface and Control Logic W B Device Features Wiper Configuration Memory POR Wiper Type Setting # of Wiper Steps (Ω) 75 75 75 7.
