DESCRIPTION
The CAT523 is a dual, 8-bit digitally-programmable
potentiometer configured for programmable voltage and
DAC-like applications. Intended for final calibration of
products such as camcorders, fax machines and cellular
telephones on automated high volume production lines,
it is also well suited for systems capable of self
calibration, and applications where equipment which is
either difficult to access or in a hazardous environment,
requires periodic adjustment.
The 2 independently programmable DPPs have a
common output voltage range which includes both
supply rails. The wipers are buffered by rail to rail OP
AMPS. Wiper settings, stored in non-volatile memory,
are not lost when the device is powered down and are
automatically reinstated when power is returned. Each
wiper can be dithered to test new output values without
effecting the stored settings and stored settings can be
read back without disturbing the DAC’s output.
Control of the CAT523 is accomplished with a simple 3
wire serial interface. A Chip Select pin allows several
CAT523's to share a common serial interface and
communication back to the host controller is via a single
serial data line thanks to the CAT523’s Tri-Stated Data
Output pin. A RDY/BSY output working in concert with
an internal low voltage detector signals proper operation
of non-volatile Erase/Write cycle.
The CAT523 is available in the 0 to 70° C Commercial
and –40° C to + 85° C Industrial operating temperature
ranges and offered in 14-pin plastic DIP and SOIC
mount packages.

* Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Absolute
Maximum Ratings are limited values applied individually while
other parameters are within specified operating conditions,
and functional operation at any of these conditions is NOT
implied. Device performance and reliability may be impaired by
exposure to absolute rating conditions for extended periods of
time.
