Overview
- 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
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 common low side. The potentiometers are separated into two groups of three 50kΩ potentiometers in parallel. Each group of three potentiometers shares a common high side and forms an equivalent resistance of 16.6kΩ (three 50kΩ potentiometers in parallel).
