CAT5241YI-00-T2

Digital Potentiometers Overview

The CAT5241YI-00-T2 is a quad digital potentiometer IC from onsemi, featuring four independent linear-taper potentiometers with 64 taps each. It integrates 16 bytes of non-volatile memory (NVRAM) to store up to four wiper settings per channel. The device operates via an I2C serial interface and supports a supply voltage range of 2.5 V to 6.0 V. Each potentiometer has an end-to-end resistance of 100 kΩ. Key electrical characteristics include a typical wiper resistance of 80 Ω at 5 V, a standby current of less than 1 µA, and an endurance rating of 1,000,000 write cycles with 100-year data retention.

Digital Potentiometers Feature Summary

• Four independent 64-tap digital potentiometers with 100 kΩ resistance
• Non-volatile memory storing four wiper settings per channel for automatic recall at power-up
• I2C serial interface supporting standard and fast mode protocols
• Industrial temperature range operation (-40°C to +85°C)

Digital Potentiometers Applications

• System level adjustments in industrial control equipment
• Automated gain or offset calibration in measurement systems
• Volume or tone control in audio processing circuits

Digital Potentiometers Procurement Notes

Verify the ordering suffix 'T2' corresponds to the TSSOP-20 package and tape & reel shipping format as specified in the datasheet. Confirm that the '-00' suffix indicates the 100 kΩ resistance value. Check for availability status as this component family may have specific lifecycle notices.

Digital Potentiometers Selection Notes

Select this part when four isolated digital potentiometers are required on a single PCB. Ensure the system voltage falls within the 2.5 V to 6.0 V range. Verify that the I2C bus speed requirements do not exceed the device's AC characteristics. Consider the 100 kΩ resistance value against load impedance requirements to ensure adequate current handling.
