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).
Applications
RF Transceivers
Voltage References
Power Supply Calibration
Mobile Phones and PDAs
Fiber Optic Transceiver Modules
Portable Electronics
Radio Tuners
Small, Low-Cost Replacement for Mechanical
