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 50k potentiometers in parallel. Each group of three potentiometers shares a common high side and forms an equivalent resistance of 16.6k (three 50k potentiometers in parallel).
