CAT5251

Quad Digital

Potentiometer (POT)

with 256 Taps

and SPI Interface

Description

http://onsemi.com

The CAT5251 is four digital POTs integrated with control logic and

16 bytes of NVRAM memory. Each digital POT 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

digital POT. 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 SPI 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 register.

The CAT5251 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

−40C to 85C industrial operating temperature range and offered in a

24-lead SOIC and TSSOP package.
