Device Block Diagram

Description:

The MCP47DA1 devices are volatile, 6-Bit digital

potentiometers with a buffered output. The wiper

setting is controlled through an I2C serial interface. The

MCP47DA1. I2C slave addresses of “010 1110” and

“011 1110” are supported. The MCP47DA1 has a

windowed output (1/3 to 2/3 of VREF).
