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 poten-
tiometers all share a common low side. The potentiome-
ters are separated into two groups of three 50k
potentiometers in parallel. Each group of three poten-
tiometers shares a common high side and forms an
equivalent resistance of 16.6k
(three 50k poten-
tiometers in parallel).
