October 1, 2009[Power Design] Fixed DC-DC Regulator Output Uses A Digitally Controlled Potentiometer
Digitally controlled potentiometers (DCPs) have become very popular in a wide variety of applications, including control, parameter adjustment, and signal processing. The digital pots replace mechanical potentiometers and provide advantages such as remote operation and programmability, higher resolution, a much smaller form factor, increased reliability, the ability to store multiple wiper positions, and lower total system cost. A...
October 2, 2008[Ideas For Design] Perform Coarse And Fine Correction With Less Costly Dual DCPS
DIGITALLY CONTROLLED POTENTIOMETERS (DCPS) find uses in a wide variety of systems for setting bias currents, variable reference voltages, and calibration settings. In industrial control and automation applications, high accuracy is a must. DCPs with 1024 taps are available, but for a few dollars instead of tens of cents. A dual, 32-tap, 50-k DCP is available for 40 cents. Can we use both of the DCPs in the package and reach similar performance to the 1024...
