settings for each potentiometer

DESCRIPTION

registers is via a 2-wire serial bus (I²C-like). On power-

up, the contents of the first data register (DR0) for each

ofthefourpotentiometersisautomaticallyloadedintoits

respective wiper control register (WCR).

The CAT5221 is two Digitally Programmable

Potentiometers (DPPs™) integrated with control logic

and 16 bytes of NVRAM memory. Each DPP consists of

with CMOS switches. A separate 6-bit control register

(WCR)independentlycontrolsthewipertapswitchesfor

each DPP. Associated with each wiper control register

are four 6-bit non-volatile memory data registers (DR)

used for storing up to four wiper settings. Writing to the

wiper control register or any of the non-volatile data

The CAT5221 can be used as a potentiometer or as a

two terminal, variable resistor. It is intended for circuit

level or system level adjustments in a wide variety of

applications.Itisavailableinthe0°Cto70°Ccommercial

and -40°C to 85°C industrial operating temperature

ranges and offered in a 20-lead SOIC package.
