CAT5221

Dual Digital

Potentiometer (POT)

with 64 Taps

and I

C Interface

Description

http://onsemi.com

The CAT5221 is two digital POTs integrated with control logic and

16 bytes of NVRAM memory. Each digital POT 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

digital POT. 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 I

C 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 (WCR).

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.
