CAT5113LI-50-G

Digital Potentiometers Overview

The CAT5113LI-50-G is a single digital potentiometer featuring a 100-tap linear taper resistor array with a nominal resistance of 50 kΩ. It operates on a single supply voltage ranging from 2.5 V to 6.0 V and draws an ultra-low standby current of 10 nA. The device utilizes a nonvolatile EEPROM to store the wiper position, ensuring settings are retained during power-down and automatically reinstated upon power restoration. Control is managed via a three-pin serial interface consisting of Chip Select (CS), Up/Down (U/D), and Increment (INC) inputs.

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance and lead finish specifications (NiPdAu for PDIP packages). Check datasheet revisions for any updates to electrical characteristics or package dimensions before finalizing procurement specifications.

Digital Potentiometers Selection Notes

Select the CAT5113LI-50-G when a 50 kΩ linear response is required. Ensure the operating temperature range matches the Industrial specification (-40°C to +85°C). Verify that the system logic levels are compatible with the CMOS input requirements and that the supply voltage remains within the 2.5 V to 6.0 V operational window.

Digital Potentiometers Part Context

This component belongs to the CAT5113 family of 100-tap digital potentiometers. The 'L' suffix indicates a PDIP-8 package, while 'I' denotes the industrial temperature range. Other variants include SOIC, TSSOP, and MSOP packages with different resistance values such as 1 kΩ, 10 kΩ, and 100 kΩ.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include CAT5113VI-50-G (SOIC-8) and CAT5113YI-50-G (TSSOP-8). For applications requiring fewer taps, consider the CAT5114 series. Verify package dimensions and thermal characteristics when substituting between different footprint types.
