CAT5113

www.DataSheet4U.com CAT5113 100-Tap Digitally Programmable Potentiometer (DPP™) FEATURES „ 100-position linear taper potentiometer „ Non-volatile EEPROM wiper storage „ 10nA ultra-low standby current „ Single supply operation: 2.5V – 6.0V „ Increment up/down serial interface „ Resistance values: 1kΩ, 10kΩ, 50kΩ and 100kΩ „ Available in PDIP, SOIC, TSSOP and MSOP packages DESCRIPTION The CAT5113 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 CAT5113 contains a 100-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, RW. The wiper setting, stored in nonvolatile memory, is not lost when the device is powered down and is automatically reinstated when power is returned. The wiper can be adjusted to test new system values without affecting the stored setting. Wiper-control of the CAT5113 is accomplished with ¯¯ , U/D ¯ , and INC ¯¯¯ . The INC ¯¯¯ three input control pins, CS input increments the wiper in the direction which is ¯ input. The CS ¯¯ determined by the logic state of the U/D input is used to select the device and also store th...
