The following literature is available on the Microchip web
site: www.microchip.com/appnotes. There are additional
application notes that may be useful.
AN219: Comparing Digital Potentiometers to Mechanical
This application note compares two types of potentiometers
– the mechanical poten tiometer (also called a trimmer
potentiometer) and the digital potentiometer. Resistor
potentiometers can be found in electronic cir cuits across a
wide spectrum of applications. Most typ ically, they function
in a voltage divider confi guration in order to execute various
types of tasks, such as offset or gain adjust.
AN691: Optimizing Digital Potentiometer Circuits to
Circuit ideas are presented that use the necessary design
techniques to mitigate errors, consequently optimizing the
performance of the digital potentiometer.
AN692: Using Digital Potentiometers to Optimize a
This application note shows how the adjustability of the
digital potentiometer can be used to an advantage in
photosensing circuits.
AN737: Using Digital Potentiometers to Design
A programmable, second-order, low-pass fi lter is presented
in four different scenarios. The fi rst three scenarios will
illustrate how a dual digital potentiometer and a single
amplifi er can be confi gured for low-pass second-order
Butterworth, Bessel and Chebyshev responses with a
programma ble corner frequency range of 1:100. An example
of the digital potentiometer setting for these designs is
summarized. The fourth scenario will show the same circuit
design, where all three approximation methods (Butterworth,
Bessel and Chebyshev) can coexist with a programmable
corner frequency range of 1:10.
AN746: Interfacing Microchip’s MCP41XXX/MCP4XXX
Communications between the MCP41XXX and MCP42XXX
family of digital potentiometers and a PIC16F876
microcontroller is discussed. These devices communicate
using a standard 3-wire SPI compatible interface. The code
supplied with this application note will include both absolute
and relocatable assembly code, written for both hardware SPI
and fi rmware SPI implementations.
