Reliability
Not susceptible to mechanical vibration & higher
tolerance to environmental factors.
Have moving parts, so can be more sensitive to
vibration, humidity, etc.
Power-up
DCPs with EEPROM will store setting until user
changes the value in memory (~100k to 1M
times).
If glue is used to prevent wiper movement, the
device setting cannot be changed.
Control
Digital control - reduced manufacturing costs and
enables factory automation
Manual control – increases setup time and
accuracy is reliant on technician
Size

Flexibility of
Output
Terminals
3 terminals allow use as either voltage divider
or variable resistor. Also allows user to change
voltage at terminal ends.
Terminals are usually fixed rail to rail. No flexibility
to change between IOUT and VOUT.
Power-up
Output Setting
Non-volatile DCPs have EEPROM where a user
can store power-up settings.
Output typically has default settings like Volatile
DCPs.
Digital
Interface
Multiple Choices: I2C, SPI, U/D, Push-button

WhAT IS A DCP?
Digitally Controlled Potentiometers are integrated circuits incorporating a resistor ladder with its associated registers, non-
volatile or volatile memory, and a digital interface providing direct communication between a host and both the resistor
ladder and memory.
register Store
DCP wiper position is stored in a
register. When power is reset, a volatile
DCP typically sets the wiper position to
midscale or zero-scale at power-up. When
the power is cycled for a nonvolatile DCP,
the last value stored in the EEPROM
register is recalled, which loads the initial
wiper value during power-up.
Digital Control
Digital control allows the user to select each
switch in a “make before break” mode,
transferring the potential to the wiper.

resistor ladder
The resistor array is comprised of individual resistors
connected in series. There are electronic switches (taps)
at each resistor junction, which have a common output
node called a wiper (VW/RW). Each physical end of the
array is described as a terminal and referred to as VH/
RH and VL/RL, and the resistance between the terminals
is referred to as RTOTAL.
