DS3930 - Hex Nonvolatile Potentiometer with I/O and Memory
The DS3930 contains six 256-bit non-volatile (NV) potentiometers, 64 bytes of NV user EEPROM memory, and four programmable NV I/O pins. All six potentiometers have a common low. The potentiometers are divided into two groups, three 50KΩ potentiometers, in parallel. Each group of three potentials shares a high side and forms an equivalent resistance of 16.6kΩ (three 50kΩ potentiometers are in parallel).
