DP7419 - Dual Digital Potentiometers

Datasheet Summary

Description

The DP7419 is two Digital Potentiometers (DPs) integrated with control logic and 16 bytes of NVRAM memory.

A separate 6-bit control register (WCR) independently controls the wiper tap position for each DP.

Features

  • Two linear-taper digital potentiometers 64 resistor taps per potentiometer End to end resistance 2.5kŸ, 10kŸ, 50kŸ or 100kŸ Potentiometer control and memory access via 2-wire Interface (I2C like) Low wiper resistance, typically 80 Four non-volatile wiper settings for each potentiometer Recall of wiper settings at power up 2.5 to 6.0 volt operation Standby current less than 1µA 1,000,000 nonvolatile WRITE cycles 100 year nonvolatile memory data retention 24-lead SOIC and 24-lead TSSOP Write prote.
