Wiper-control
of
the
CAT5112
is
accomplished with three input control pins,
CS, U/D,
and
INC. The INC input increments the wiper in the
direction which is determined by the logic state of
the U/
D input. The CS input is used to select the
device and also store the wiper position prior to
power down.
The digitally programmable potentiometer can be
used as a buffered voltage divider. For applications
where the potentiometer is used as a 2-terminal variable
resistor, please refer to the CAT5114. The buffered
wiper of the CAT5112 is not compatible with that appli-
cation. DPPs bring variability and programmability to a
broad range of applications and are used primarily to
control, regulate or adjust a characteristic or parameter
of an analog circuit.
FUNCTIONAL DIAGRAM
DESCRIPTION
The CAT5112 is a single digitally programmable
potentiometer (DPP™) designed as a electronic
replacement for mechanical potentiometers and trim
pots. Ideal for automated adjustments on high volume
production lines, they are also well suited for
applications where equipment requiring periodic
adjustment is either difficult to access or located in a
hazardous or remote environment.
The CAT5112 contains a 32-tap series resistor array
connected between two terminals RH and RL. An up/
down counter and decoder that are controlled by three
input pins, determines which tap is connected to the
wiper, RWB. The CAT5112 wiper is buffered by an op
amp that operates rail to rail. The wiper setting, stored in
non-volatile NVRAM memory, is not lost when the de-
vice is powered down and is automatically recalled when
power is returned. The wiper can be adjusted to test new
