DS3930 Datasheet Hex Nonvolatile Potentiometer

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: DS3930 Rev 0; 4/03 Hex Nonvolatile Potentiometer with I/O and Memory.

General Description

The DS3930 contains six 256-position nonvolatile (NV) potentiometers, 64 bytes of NV user EEPROM memory, and four programmable NV I/O pins.

The six potentiometers all share a mon low side.

The potentiometers are separated into two groups of three 50kΩ potentiometers in parallel.

Key Features

  • Six 256-Position NV Potentiometers.
  • Four General-Purpose NV I/O Pins.
  • 64 Bytes of User EEPROM Memory.
  • 0 to 5.5V on Any Potentiometer Terminal, Independent of VCC.
  • All Six Potentiometers Share a Common Low Side.
  • Potentiometers Separated into Two Groups of Three Potentiometers, Each Sharing a Common High Side.
  • 2-Wire Serial Interface.
  • Wide Supply Range (2.7V to 5.5V).
  • Up to Eight DS3930s Can Share the Same 2-Wire Bus.
