CAT5259/D
CAT5259
Quad Digital
Potentiometer (POT)
with 256 Taps
and I2C Interface
Description
The CAT5259 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
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 I2C 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 0C
to 70C commercial and 40C to 85C industrial operating
temperature ranges and offered in a 24-lead SOIC and TSSOP
package.
