MCP42010

M Features 256 taps for each potentiometer Potentiometer values for 10 kΩ, 50 kΩ and 100 kΩ Single and dual versions SPI™ serial interface (mode 0,0 and 1,1) ±1 LSB max INL & DNL Low power CMOS technology 1 µA maximum supply current in static operation Multiple devices can be daisy-chained together (MCP42XXX only) Shutdown feature open circuits of all resistors for maximum power savings Hardware shutdown pin available on MCP42XXX only Single supply operation (2.7V - 5.5V) Industrial temperature range: -40°C to +85°C Extended temperature range: -40°C to +125°C MCP41XXX/42XXX Description 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 an industry-standard SPI interface. The devices consume <1 µA during static operation. A software shutdown feature is provided that disconnects the “A” terminal from the resistor stack and simultaneously connects the wiper to the “B” terminal. In addition, the dual MCP42XXX has a SHDN pin that performs the same function in hardware. During shutdown mode, the contents of the wiper register can be changed and the potentiometer returns from shutdown to the new value. The wiper is reset to t...
