CAT5113LI-50

Digital Potentiometers Overview

The CAT5113LI-50 is a single-channel digital potentiometer manufactured by onsemi. It features a resistance value of 50 kOhms with a linear taper and a tolerance of 20%. The device provides 100 taps for precise wiper positioning and utilizes non-volatile memory to retain settings without power. It operates within a supply voltage range of 2.5 V to 6 V, consuming a typical current of 100 uA. The component supports a serial 3-wire interface and functions across an extended temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power loss
• Single channel with 100 tap resolution
• Linear taper characteristic with 50 kOhm total resistance
• Low power consumption of 100 uA typical operating current

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference trimming
• System calibration requiring persistent settings

Digital Potentiometers Procurement Notes

Verify the specific package type and suffix codes when sourcing, as variations exist within the CAT5113 family. Confirm end-of-life status or availability through authorized distributors, as discontinuance notifications may apply. Ensure compatibility with the required serial interface protocol before integration into existing designs.

Digital Potentiometers Selection Notes

Select this model for applications requiring a single potentiometer with high resolution (100 taps) and non-volatile storage. Compare against the CAT5112 series if fewer taps (32) are sufficient, or consider alternative packages like MSOP-8 or TSSOP-8 depending on board space constraints. Verify that the 50 kOhm resistance value matches the circuit requirements.

Digital Potentiometers Part Context

This component belongs to the CAT51x series of linear-taper digital potentiometers from onsemi. These devices are designed to replace mechanical potentiometers in systems where size, reliability, and programmability are critical. The series offers various resistance values and packaging options to suit different embedded system needs.

Digital Potentiometers Replacement Considerations

Direct replacements include other CAT5113 variants with different package suffixes such as CAT5113ZI-50-G or CAT5113VI-50-G. Ensure the substitute maintains the same 50 kOhm resistance, 100 tap count, and non-volatile memory feature set.
