Description

Applications

The MCP47A1 devices are volatile, 6-Bit digital

potentiometers with a buffered output. The wiper

setting is controlled through an I²C serial interface. The

I²C slave addresses of “010 1110”and “011 1110”

are supported.

• Set point or offset trimming

• Cost-sensitive mechanical trim pot replacement
