Digitally Programmable Potentiometers
Wiper position is stored in nonvolatile memory and is not lost when device power is removed. In addition, wiper position can be adjusted to test new system values without changing the stored wiper position. The CAT5111 uses a buffer configured operational amplifier to minimize errors if there is potential wiper loading. Operating voltage range is 2.5 volts to 6.0 volts. Supply current is a low 100° microamperes maximum.
The CAT5111 and CAT5113 have the same pinout.
Potential applications include optical networking, telecommunications, instrumentation, white goods, power supplies, power meters, temperature controllers, smart instruments, personal communication devices, office equipment, automatic test equipment, Internet appliances, cell phones, industrial process controllers and communication systems.
