FUNCTIONAL DESCRIPTION
The CAT5110/5118/5119/5123/5124/5125 consist of a
fixed resistor and a wiper contact with 32tap points that are
digitally controlled through a 2-wire up/down serial
interface. Three end-to-end resistance values are available:
10 k
W, 50 kW and 100 kW.
The CAT5110/5125 is designed to operate as a
potentiometer. In this configuration, the low terminal of the
resistor array is connected to ground (pin 2).
The CAT5118/5123 performs as a variable resistor. In this
device, the wiper terminal and high terminal of the resistor
array are connected at pin 5. The CAT5119/5124 is a similar
variable resistor, except the low terminal is connected to
pin 5.
Digital Interface Operation
The devices have two modes of operation when the serial
interface is active: increment and decrement mode. The
serial interface is only active when CS is low.
The CS and U/D inputs control the position of the wiper
along the resistor array. When CS transitions from high to
low, the part will go into increment mode if U/D input is
high, and into decrement mode when U/D input is low. Once
the mode is set, the device will remain in that mode until CS
goes high again. A low-to-high transition at the U/D pin will
increment or decrement the wiper position depending on the
When the CS input transitions to high (serial interface
inactive), the value of the counter is stored and the wiper
position is maintained.
Note that when the wiper reaches the maximum (or
minimum) tap position, the wiper will not wrap around to the
minimum (or maximum) position.
Power-On Reset
All parts in this family feature power-on reset (POR)
circuitry that sets the wiper position to midscale at
power-up. By default, the chip is in the increment mode.
