Digital Potentiometers datasheet and documents for CAT5241WI-10-QJ
Digital Potentiometers Overview
The CAT5241WI-10-QJ is a quad digital potentiometer IC from onsemi, featuring four independent 64-tap wipers with non-volatile memory. It utilizes an I2C serial interface for control and operates within a supply voltage range of 2.5 V to 6 V. The device offers a resistance value of 10 kOhms with a linear taper and a temperature coefficient of 300 PPM/°C. Designed for surface-mount installation, it is housed in a 20-SOIC package and supports an operating temperature range from -40°C to +85°C.
Digital Potentiometers Feature Summary
- Quad configuration with four 64-position wipers
- Non-volatile NVRAM for wiper position storage
- I2C serial control interface
- 10 kOhms resistance with linear taper
Digital Potentiometers Applications
- Automated product calibration
- Remote control adjustment of equipment
- Offset, gain, and zero adjustments in self-calibrating systems
Digital Potentiometers Procurement Notes
Verify the 'QJ' suffix against official onsemi documentation to confirm automotive qualification status (AEC-Q100). Confirm current production lifecycle status as previous variants in this series have been marked obsolete. Ensure compatibility with existing PCB footprints for the 20-SOIC package before procurement.
Digital Potentiometers Selection Notes
Select this component when a quad digital potentiometer with non-volatile memory and I2C control is required. Verify that the 10 kOhms resistance and 64-tap resolution meet circuit requirements. Ensure the operating environment stays within the specified -40°C to +85°C temperature range and the supply voltage remains between 2.5 V and 6 V.
Digital Potentiometers Part Context
This part belongs to the CAT5241 family of digitally programmable potentiometers. It shares core specifications with variants like the CAT5241YI-10-T2 but differs in packaging (SOIC vs TSSOP) and potential qualification grades indicated by the suffix. The family is designed for applications requiring precise, digitally adjustable resistance or voltage division.
Digital Potentiometers Replacement Considerations
Direct substitutes include other CAT5241 variants such as CAT5241YI-10-T2 or CAT5241WI-10-T1, provided the package type (TSSOP-20 vs SOIC-20) and specific suffix qualifications are verified for pinout and electrical equivalence.
