CAT5261YI00

Digital Potentiometers Overview

The CAT5261YI00 is a dual-channel digital potentiometer manufactured by onsemi, housed in a 24-TSSOP surface-mount package. It features two independent circuits, each providing 256 tap positions with a total resistance of 100 kOhms. The device operates within a supply voltage range of 2.5V to 6V and includes non-volatile memory to retain wiper settings. It functions reliably across an industrial temperature range of -40°C to +85°C, with a typical temperature coefficient of 300ppm/°C.

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or certified suppliers. Confirm the specific manufacturing date code and lot number against current inventory records. Check for RoHS compliance status and ensure the package matches the 24-TSSOP specification. Validate that the part meets the required operating temperature range for the intended application environment.

Digital Potentiometers Selection Notes

Select this component when a dual-channel configuration with high resolution (256 taps) is required. Ensure the system interface supports the necessary control protocol for the digital potentiometer. Verify that the 100 kOhm resistance value aligns with the circuit's impedance requirements. Consider the 2.5V to 6V supply voltage range to ensure compatibility with the system power rails.

Digital Potentiometers Part Context

This part belongs to the CAT5261 family of digital potentiometers from onsemi. It serves as a solid-state alternative to traditional mechanical potentiometers, offering improved reliability and programmability. The device integrates control logic and non-volatile memory into a compact form factor suitable for space-constrained electronic designs.

Digital Potentiometers Replacement Considerations

Check for direct pin-to-pin replacements within the same manufacturer's portfolio. Verify that any substitute component maintains identical electrical parameters, including resistance tolerance, tap count, and memory type. Ensure the replacement package matches the 24-TSSOP dimensions for board compatibility.
