PIN DESCRIPTIONS
CS
The chip select input is used to activate the control
input of the CAT5115 and is active low. When in a
high state, activity on the INC
affect or change the position of the wiper.
DEVICE OPERATION
The CAT5115 operates like a digitally controlled
potentiometer with R
and low terminals and R
mechanical potentiometer's wiper. There are 32
available tap positions including the resistor end
points, R
connected in series between the R
The wiper terminal is connected to one of the 32 taps
and controlled by three inputs, INC
These inputs control a five-bit up/down counter whose
output is decoded to select the wiper position.
With CS
respond to the U/D ¯ and INC
transitions on INC
wiper (depending on the state of the U/D ¯ input and
five-bit counter). The wiper, when at either fixed
terminal, acts like its mechanical equivalent and does
not move beyond the last position. When the
CAT5115 is powered-down, the wiper position is
reset. When power is restored, the counter is set to
the mid point, tap 15.
