DESCRIPTION
The CAT5111 is a single digitally programmable
potentiometer (DPP™) designed as a electronic
replacement for mechanical potentiometers. 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 CAT5111 contains a 100-tap series resistor array
connected between two terminals R
up/down counter and decoder that are controlled by
three input pins, determines which tap is connected to
the wiper, R
op amp that operates rail to rail. The wiper setting,
stored in non-volatile memory, is not lost when the
device is powered down and is automatically recalled
when power is returned. The wiper can be adjusted to
test new system values without effecting the stored
setting.
accomplished with three input control pins, CS
and INC
direction which is determined by the logic state of the
U/D ¯ input. The CS
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 CAT5113. The
buffered wiper of the CAT5111 is not compatible with
that application.
