Catalyst
semiconductor adds 5 new 32-tap Digitally Programmable Potentiometers.
These new potentiometers from Catalyst are silicon based
and offer a user-friendly up/down interface. The CAT5123,
CAT5124 and CAT5125 are volatile type and offer pin-for-pin
replacements for Maxim's MAX5466, MAX5467 and MAX5468 devices.
The CAT5127 and CAT5129 features on chip, non-volatile,
EPROM memory by which if the designers once calibrate can
retain the memory settings even if power is lost. The wiper
can be preset to any position on the device and when power
up the wiper go to the preset position. They offer pin-for-pin
replacements for Intersil's X93154.
These are small in size and are best suited for LCD screen
adjustment, automated calibration, contrast, brightness
and volume control, gain adjustment, line impedance matching,
mechanical potentiometer replacement in handheld and other
space-constrained applications. They offer low noise, insensitive
to mechanical vibrations, shock, oxidation, and best alternatives
to DACs and mechanical potentiometers.
