Datasheet	CAT5269_CatalystSemiconductor.pdf

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.

The tap points between each resistive element are connected to the wiper outputs with CMOS switches.

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.
