CAT522
Configured Digitally Programmable Potentiometer (DPP™):
Programmable Voltage Applications
FEATURES
Two 8-bit DPPs configured as programmable
voltage sources in DAC-like applications
Independent reference inputs
Non-volatile NVRAM memory wiper storage
Output voltage range includes both supply rails
2 independently addressable buffered
output wipers
1 LSB accuracy, high resolution
Serial Microwire-like interface
Single supply operation: 2.7V - 5.5V
Setting read-back without effecting outputs
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 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.
For Ordering Information details, see page 14.
APPLICATIONS
Automated product calibration.
Remote control adjustment of equipment
Offset, gain and zero adjustments in self-
calibrating and adaptive control systems.
Tamper-proof calibrations.
DAC (with memory) substitute.

Notes:
(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this
specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.
(2) This parameter is tested initially and after a design or process change that affects the parameter.
(3) Latch-up protection is provided for stresses up to 100mA on address and data pins from –1V to V
