• Extended temperature range: -40°C to +125°C The MCP41XXX and MCP42XXX devices are 256position, digital potentiometers available in 10 kΩ,
50 kΩ and 100 kΩ resistance versions. The
MCP41XXX is a single-channel device and is offered in
an 8-pin PDIP or SOIC package. The MCP42XXX contains two independent channels in a 14-pin PDIP, SOIC
or TSSOP package. The wiper position of the
MCP41XXX/42XXX varies linearly and is controlled via …
