CAT5261
Dual Digital
Potentiometer (POT)
with 256 Taps
and SPI Interface
Description
The CAT5261 is two digital POTs integrated with control logic and
8 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
register (WCR) independently controls the wiper tap switches for each
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 potentiometers
is automatically loaded into its respective wiper control register.
The CAT5261 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
40C to 85C industrial operating temperature range and offered in a
24-lead SOIC and TSSOP package.
