CAT5241WI-00

Digital Potentiometers Overview

The CAT5241WI-00 is a quad digitally programmable potentiometer (DPP) manufactured by onsemi. It features four independent potentiometers, each with 64 taps and non-volatile memory for wiper position storage. The device utilizes an I2C serial interface for control and operates within a supply voltage range of 2.5 V to 6 V. The total resistance value is specified as 0 Ω, indicating a configuration as variable resistors or shorting elements rather than traditional potentiometric dividers. Key electrical parameters include a temperature coefficient of 300 ppm/°C and a tolerance of 20%.

Digital Potentiometers Feature Summary

• Quad architecture with four independent 64-tap digital potentiometers.
• Non-volatile NVRAM stores wiper positions upon power-down.
• I2C compatible serial control interface.
• Operates on a single supply voltage from 2.5 V to 6 V.

Digital Potentiometers Applications

• Automated product calibration in high-volume production lines.
• Remote adjustment of equipment in hazardous or inaccessible environments.
• Offset, gain, and zero adjustments in self-calibrating systems.
• Tamper-proof calibration settings.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'WI-00' against the official onsemi datasheet to confirm the 0 Ω resistance value and SOIC-20 package type. Check current lifecycle status as older variants may be discontinued. Ensure I2C address configurations match system requirements before integration.

Digital Potentiometers Selection Notes

Select this component when a quad-channel solution with non-volatile memory is required. The 0 Ω specification suits applications needing digitally controlled variable resistors or switches. Confirm that the I2C bus speed and voltage levels are compatible with the host controller. Compare with CAT5241YI-00 if TSSOP packaging is preferred over SOIC.

Digital Potentiometers Part Context

This part belongs to the CAT5241 family of quad digital potentiometers. It shares functional similarities with other members like CAT5241YI-50 but differs in resistance value and package style. The family is designed to replace mechanical potentiometers in automated testing and calibration scenarios.

Digital Potentiometers Replacement Considerations

Direct substitutes include CAT5241YI-00 for pin-compatible TSSOP-20 alternatives. Verify interface compatibility and memory retention features when cross-referencing with other quad DPPs from different manufacturers.

Digital Potentiometers FAQ

What does the '00' suffix indicate in the model number?

The '00' suffix indicates a total resistance value of 0 Ω, configuring the devices as variable resistors rather than potentiometers.

How many taps does each potentiometer have?

Each of the four potentiometers has 64 taps, providing 64 discrete resistance steps.

Is the wiper position retained after power loss?

Yes, the device includes non-volatile NVRAM that automatically saves the wiper position when power is removed.
