FEATURES
32-position linear taper potentiometer Non-volatile EEPROM wiper storage Low standby current Single supply operation: 2.5V – 5.5V Increment Up/Down serial interface Resistance values: 10kΩ, 50kΩ and 100kΩ CAT5127 in tiny 8 lead 2mmx2.5mm TDFN and MSOP packages CAT5129 in the 6 lead TSOT23 package DESCRIPTION
The CAT5127/CAT5129 are single digitally program– mable potentiometers (DPP™) designed as a electro– nic 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 CAT5127 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. Wiper-control of the CAT5127/CAT5129 is ¯¯ , U/D ¯, accomplished with three input control pins, CS ¯¯¯ .
