Digital Pots Maintain Settings Following Power Loss

These digital potentiometers perform the same electronic adjustment function as a mechanical pot or variable resistor, yet offer solid-state reliability and compact packaging. Available in single-, dual- and quad-channel models with a range of setting options (1024 positions for the single AD5231, 256 positions for the dual AD5232 and 64 positions for the quad AD5233), the programmable devices allow multiple modes of operation and adjustment, including direct program setting, increment/decrement control, right/left shift for 6 dB changes, and a pulse mode for direct pushbutton control. The devices come in 16- and 24-lead TSSOPs and are well suited for optical networking, instrumentation and telecomm applications. They are also designed for precision adjustment applications such as power supply voltages, sensors, LED laser intensity levels, and gyro sensors, and are ideal replacements for mechanical potentiometers. In 100-piece quantities, the AD5231 costs $2.20, the AD5232 is priced at $2.95, and the AD5233 sells for $3.95. ANALOG DEVICES INC., Wilmington, MA. (781) 937-1989.
