DESCRIPTION

The CAT5259 is four digitally programmable

potentiometers (DPPs™) integrated with control logic

and 16 bytes of NVRAM memory. Each DPP consists of

a series of 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 8-bit control register

(WCR) independently controls the wiper tap switches for

each DPP. Associated with each wiper control register

are four 8-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. 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 registers.

The CAT5259 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. It is available in the 0˚C to 70˚C commercial

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

ranges and offered in a 24-lead SOIC and TSSOP

package.
