AN747: Communicating with Daisy Chained MCP42XXX
Digital Potentiometers
The MCP41XXX and MCP42XXX family of digital
potentiometers allow for daisy chaining of multiple devices
on a single SPI bus. It is possible to communicate to multiple
devices using one 3-wire data bus (CS, CLK and DATA), by
connecting the SO pin on one device to the SI pin of the
next device in the chain. This application note details one
example of source code that is used to communicate with
eight daisy chained devices.
AN757: Interfacing Microchip’s MCP41XXX/MCP4XXX
Digital Potentiometer to the Motorola 68HC12
Microcontroller
Communication between the MCP41XXX and MCP42XXX
family of digital potentiometers and the Motorola 68HC12
family of microcontrollers is discussed. These devices
communicate using a standard 3-wire SPI compatible
interface. Specically, the MC68HC912B32 evaluation board
was used.
AN1080: Understanding Digital Potentiometer Resistance
Variations
This application note discusses how process, voltage and
temperature effect the resistor network’s characteristics,
specifications and techniques to improve system
performance.
AN1316: Using Digital Potentiometers for Programmable
Amplier Gain
This Application Note will discuss implementations of
programmable gain circuits using an op amp and a digital
potentiometer. This discussion will include implementation
details for the digital potentiometer’s resistor network. It is
important to understand these details to understand the
effects on the application.
