Configured Digitally Programmable Potentiometer (DPP™):

Programmable Voltage Applications

FEATURES

DESCRIPTION

Four 8-bit DPPs configured as programmable

The CAT525 is a quad 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 and systems capable of self

calibration, it is also well suited for applications were

equipment requiring periodic adjustment is either difficult

to access or located in a hazardous environment.

voltage sources in DAC-like applications

Independent reference inputs

Buffered wiper outputs

Non-volatile NVRAM memory wiper storage

Output voltage range includes both supply rails

4 independently addressable buffered output

wipers

1 LSB accuracy, high resolution

Serial Microwire-like interface

The CAT525 offers four 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 op amps. 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.

Single supply operation: 2.7V - 5.5V

Setting read-back without effecting outputs

For Ordering Information details, see page 14.

APPLICATIONS

Automated product calibration

Control of the CAT525 is accomplished with a simple

3wire, Microwire-like serial interface. A Chip Select pin

allows several CAT525's to share a common serial

interface and communications back to the host

controller is via a single serial data line thanks to the

Remote control adjustment of equipment

Offset, gain and zero adjustments in self-

calibrating and adaptive control systems
