CAT5401YI-10

Digital Potentiometers Overview

The CAT5401YI-10 is a single-channel Digitally Programmable Potentiometer (DPP) manufactured by onsemi. It features a resistance value of 10 kOhms with a linear taper and 20% tolerance. The device provides 100 taps for precise resistance adjustment and includes non-volatile memory to retain settings without power. It operates on a supply voltage between 2.5 V and 6 V, consuming approximately 200 µA. The component utilizes a serial digital interface and is housed in a TSSOP-24 package suitable for surface mount applications.

Digital Potentiometers Feature Summary

• Single potentiometer channel with 100-tap resolution
• Non-volatile memory retains wiper position after power loss
• Linear taper with 10 kOhms nominal resistance
• Serial digital control interface

Digital Potentiometers Applications

• Audio volume control circuits
• Programmable gain amplifier biasing
• Voltage reference adjustment
• Sensor calibration systems

Digital Potentiometers Procurement Notes

Verify the specific suffix 'YI' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Check for obsolescence status as older batches may be discontinued. Ensure the serial interface protocol matches the system controller requirements before integration.

Digital Potentiometers Selection Notes

Select this component when a single-channel, high-resolution (100-tap) digitally adjustable resistor is required. The 10 kOhms value suits moderate impedance applications. Verify that the 2.5 V to 6 V operating range aligns with the target system voltage. Consider the TSSOP-24 package size constraints during PCB layout.

Digital Potentiometers Part Context

This part belongs to the CAT5401 family of Quad Digitally Programmable Potentiometers. While the base model typically offers four channels, the CAT5401YI-10 variant specifies a single channel configuration within the same series architecture. It shares design characteristics with other CAT54xx devices but differs in channel count and specific resistance values.

Digital Potentiometers Replacement Considerations

Direct substitutes include other single-channel DPPs from onsemi such as the CAT5120 series, though tap counts and interfaces may differ. Cross-reference with CAT5401WI-10 for potential packaging variations. Verify electrical parameters match exactly before substitution.
