CAT5113Z-10-TE13

Digital Potentiometers Overview

The CAT5113Z-10-TE13 is a single-channel digital potentiometer from the onsemi CAT5113 series, designed as an electronic replacement for mechanical potentiometers. It features a 10 kΩ resistance value with a linear taper and 100 adjustable taps. The device utilizes non-volatile EEPROM to store wiper positions, ensuring settings are retained during power loss. It operates on a single supply voltage ranging from 2.5 V to 6.0 V with a typical standby current of 10 nA. Control is managed via a serial interface using CS, U/D, and INC pins. The component is housed in an 8-pin MSOP package.

Digital Potentiometers Feature Summary

• 100-position linear taper potentiometer with 10 kΩ nominal resistance
• Non-volatile EEPROM storage retains wiper position after power-down
• Ultra-low standby current of 10 nA
• Single supply operation: 2.5 V to 6.0 V

Digital Potentiometers Applications

• Automated product calibration
• Remote control adjustments
• Offset, gain, and zero control circuits
• Tamper-proof calibration systems

Digital Potentiometers Procurement Notes

Verify the specific suffix 'Z' against official onsemi documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through the manufacturer's latest material declaration. Check for end-of-life notices or obsolescence warnings prior to procurement planning.

Digital Potentiometers Selection Notes

Select this component when a 100-tap resolution is required for precise analog adjustment. Ensure the application supports the 2.5 V to 6.0 V operating range. Verify that the MSOP-8 package fits the PCB layout constraints. Compare against the CAT5112 if only 32 taps are sufficient for the design requirements.

Digital Potentiometers Part Context

This part belongs to the CAT5113 family of digitally programmable potentiometers originally developed by Catalyst Semiconductor and now manufactured by onsemi. The series offers various resistance values (1k, 10k, 50k, 100k) and packages including SOIC, TSSOP, and MSOP. The Z suffix typically denotes the MSOP package variant within this product line.

Digital Potentiometers Replacement Considerations

Direct replacements include other CAT5113 variants with different resistance values or packages, such as CAT5113YI-10-GT3 (TSSOP) or CAT5113ZI-10-T3 (MSOP). Cross-reference with similar 100-tap digital pots from manufacturers like Microchip or Analog Devices if sourcing issues arise.
