DESCRIPTION
The CAT522 is a dual, 8-bit digitally-programmable
potentiometer (DPP™) 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
self-calibrating systems and for applications where
equipment which requires periodic adjustment is either
difficult to access or in a hazardous environment.
The CAT522 offers two independently programmable
DPPs each having its own reference inputs and each
capable of rail to rail output swing. The wipers are
buffered by rail to rail opamps. Wiper settings, stored in
non-volatile NVRAM memory, are not lost when the
device is powered down and are automatically
reinstated when power is returned. Each wiper can be

PIN CONFIGURATION
dithered to test new output values without effecting the
stored settings and stored settings can be read back
without disturbing the DPP's output.
The CAT522 is controlled with a simple 3-wire, microwire-
like serial interface. A Chip Select pin allows several
devices to share a common serial interface.
Communication back to the host controller is via a single
serial data line thanks to the CAT522 Tri-Stated Data
Output pin. A RDY/
BSY output working in concert with
an internal low voltage detector signals proper operation
of the non-volatile NVRAM memory Erase/Write cycle.
The CAT522 is available in the 0
°C to 70°C commercial
and -40
°C to 85°C industrial operating temperature
ranges. Both 14-pin plastic DIP and surface mount
packages are available.
