DESCRIPTION

· The MCP41XXX and MCP42XXX are 256-position digital potentiometers with resistance values of 10 kΩ, 50 kΩ, and 100 kΩ.
· MCP41XXX is a single-channel device in an 8-pin PDIP or SOIC package.
· MCP42XXX contains two independent channels in a 14-pin PDIP, SOIC, or TSSOP package.
· The wiper position is controlled via an SPI interface, with a reset to mid-scale (80h) upon power-up.
· The devices operate from a single 2.7 - 5.5V supply and are specified for industrial and extended temperature ranges.

FEATURES

· 256 taps for each potentiometer.
· Available in 10 kΩ, 50 kΩ, and 100 kΩ resistance versions.
· Single (MCP41XXX) and dual (MCP42XXX) versions.
· SPI™ serial interface (mode 0,0 and 1,1).
· ±1 LSB max INL & DNL.
· Low power CMOS technology with <1 µA supply current in static operation.
· Daisy-chaining capability for multiple devices (MCP42XXX only).
· Shutdown feature for maximum power savings.
· Hardware shutdown pin available on MCP42XXX.
· Single supply operation (2.7V - 5.5V).
· Industrial temperature range: -40°C to +85°C.
· Extended temperature range: -40°C to +125°C.

APPLICATIONS

· Digital potentiometers for precision control in various electronic systems.
· Suitable for applications requiring low power consumption and high reliability.
· Ideal for industrial and extended temperature environments.
· Used in systems where multiple devices need to be daisy-chained for synchronized control.
