CAT524WI-T2

Digital Potentiometers Overview

The CAT524WI-T2 is a quad digital potentiometer IC from onsemi, featuring four independent channels with 8-bit resolution. It utilizes an I2C serial interface for control and offers a resistance value of 24 kOhms per channel. The device operates within a supply voltage range of 2.5 V to 6 V and includes non-volatile memory to retain wiper settings during power loss. Packaged in a 14-SOIC format, it supports linear taper characteristics and functions across a temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad-channel architecture providing four independent digital potentiometers within a single package
• Non-volatile memory capability ensures retention of wiper position settings after power cycles
• I2C serial interface enables simplified communication and control using only two bus lines

Digital Potentiometers Applications

• Audio volume and tone control circuits requiring multi-channel adjustment
• Programmable gain amplifier configurations in signal processing systems
• Voltage reference and bias level setting in sensor interfaces

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T2' corresponds to the required tape-and-reel packaging configuration when ordering. Confirm that the 24 kOhm resistance value aligns with circuit requirements, as other variants in the series offer different resistance values. Ensure the I2C address configuration matches the system design to avoid bus conflicts.

Digital Potentiometers Selection Notes

Select this component when a quad-channel solution is necessary to save board space compared to discrete potentiometers. The non-volatile feature is critical for applications where the last known state must be restored immediately upon power-up without re-initialization. Verify that the 24 kOhm resistance and 8-bit resolution meet the precision and load requirements of the target application.

Digital Potentiometers Part Context

This part belongs to the CAT524 family of digital potentiometers, which are designed as direct replacements for traditional mechanical potentiometers. The family provides reliable electronic adjustment with no moving parts, offering improved durability and longer operational life in harsh environments compared to mechanical alternatives.

Digital Potentiometers Replacement Considerations

Check datasheets for CAT524xI-W2 or CAT524xW-I variants if different packaging or temperature ratings are needed. Ensure substitute parts maintain the same 24 kOhm resistance and quad-channel configuration to guarantee electrical compatibility.
