DESCRIPTION

The CAT5241 is four Digitally Programmable

Potentiometers (DPPs™) integrated with control logic

and 16 bytes of NVRAM memory. Each DPP consists of

a series of 63 resistive elements connected between two

externally accessible end points. The tap points between

each resistive element are connected to the wiper outputs

with CMOS switches. A separate 6-bit control register

(WCR) independently controls the wiper tap switches for

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

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

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

of the four potentiometers is automatically loaded into its

respective wiper control register (WCR).

The CAT5241 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.
