DS3930 Datasheet | Maxim Integrated

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