CAT5269
Dual Digital
Potentiometer (POT)
with 256 Taps
and 2‐wire Interface
Description
http://onsemi.com
The CAT5269 is two digital POTs integrated with control logic and
18 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 2-wire 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 registers.
The CAT5269 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.

A newbie has an urgent question about 2812ad sampling!
The sampling value of 2812 is a few tenths of a volt different from the actual analog voltage input. For a 1.1 volt input, the sampled value is about 1.2 or 1.3 volts. And the repeated sampling values...
