Additional preview pages of the CAT5269 datasheet.

The CAT5259 is two digitally programmable poten

tiometers (DPPs™) integrated with control logic and 18 bytes of NVRAM memory.

Each DPP consists of a series of resistive elements connected between two externally accessible end points.

Four linear taper digitally programmable potentiometers.
256 resistor taps per potentiometer.
End to end resistance 50kΩ or 100kΩ.
Potentiometer control and memory access via 2-wire interface (I2C like).
Low wiper resistance, typically 100Ω.
Nonvolatile memory storage for up to four wiper settings for each potentiometer.
Automatic recall of saved wiper settings at power up.
2.5 to 6.0 volt operation.
Standby curren.
