CAT5401YI-10-T2

Digital Potentiometers Overview

The CAT5401YI-10-T2 is a quad digital potentiometer IC from onsemi, featuring four independent wipers with non-volatile memory. Each potentiometer offers 64 taps and utilizes an SPI serial interface for control. The device operates within a supply voltage range of 2.5 V to 6 V, with a typical operating current of 1 mA. It employs a linear taper profile and is housed in a 24-pin TSSOP package. This component serves as a solid-state replacement for mechanical potentiometers in applications requiring programmable resistance settings.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 64-tap digital potentiometers
• Non-volatile memory retains wiper position after power loss
• SPI serial interface for digital control
• Linear taper resistance profile

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Digital volume control in audio circuits

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T2' against official datasheets to confirm tape and reel packaging specifications. Confirm that the '10' designation corresponds to the 10 kOhm resistance value, as this differs from other variants like the CAT5401YI-00. Check for End-of-Life (EOL) status notifications, as discontinuance may affect long-term availability.

Digital Potentiometers Selection Notes

Select this part when a quad-channel digital potentiometer with non-volatile storage is required. Ensure the system supports SPI communication protocols. Verify that the 10 kOhm resistance value fits the circuit design requirements compared to other available values such as 1 kOhm or 100 kOhm. The TSSOP-24 package must be compatible with the PCB footprint constraints.

Digital Potentiometers Part Context

This component belongs to the CAT5401 series of digital potentiometers. It shares architectural similarities with other members of the family but is distinguished by its quad channel count and specific resistance value. The series is designed to replace mechanical pots in space-constrained designs where reliability and programmability are prioritized.

Digital Potentiometers Replacement Considerations

Direct substitutes include other CAT5401 variants with different resistance values (e.g., CAT5401YI-00-T2 for 100 kOhm). Cross-reference with CAT5411 series if only dual channels are needed. Verify pinout compatibility before swapping with similar quad digital potentiometers from other manufacturers.
