CAT5241YI-10-T2

Digital Potentiometers Overview

The CAT5241YI-10-T2 is a quad digital potentiometer IC from onsemi, featuring four independent linear-taper potentiometers with 64 taps each. It integrates I2C serial interface logic and 16 bytes of non-volatile RAM (NVRAM) for storing up to four wiper settings per channel. The device operates within a supply voltage range of 2.5 V to 6.0 V and supports industrial temperatures from -40°C to +85°C. Key electrical parameters include a typical power supply current of 1 mA, standby current under 1 µA, and end-to-end resistance tolerance of ±20%. The unit is housed in a 20-lead TSSOP package.

Digital Potentiometers Feature Summary

• Four independent 64-tap linear digital potentiometers with I2C control
• Non-volatile memory stores four wiper positions per potentiometer for automatic recall at power-up
• Low wiper resistance typically 80 Ω at 5 V supply
• Industrial temperature range (-40°C to +85°C) with 2.5 V to 6.0 V operation

Digital Potentiometers Applications

• Circuit level adjustments requiring digital control
• System level calibration and trimming
• Automated production line adjustments
• Remote or hazardous environment equipment adjustment

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'T2' corresponds to the TSSOP-20 package and tape & reel shipping format as defined in the manufacturer's ordering information. Confirm that the 'I' suffix indicates the industrial temperature grade. Ensure compatibility with the required I2C bus addressing scheme using the A0-A3 pins.

Digital Potentiometers Selection Notes

Select this component when four isolated digital potentiometers are required in a single package. The 10 kΩ resistance value is specified by the '-10' suffix. The Y suffix denotes the TSSOP-20 package. Verify that the system can support the I2C protocol and that the 64-tap resolution meets the application's precision requirements.

Digital Potentiometers Part Context

This part belongs to the CAT5241 family of quad digital potentiometers. Variants differ by resistance value (2.5k, 10k, 50k, 100k), package type (SOIC-20 or TSSOP-20), and shipping method (tube or tape & reel). The CAT5241YI-10-T2 specifically combines the 10 kΩ resistance, TSSOP-20 package, and tape & reel packaging.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include CAT5241WI-10-T1 (SOIC-20 package) or CAT5241YI-10 (TSSOP-20 tube). Other families like CAT5120 or CAT5125 offer different tap counts and interfaces and are not direct substitutes.
