CAT5259WI-00-T1

Digital Potentiometers Overview

The CAT5259WI-00-T1 is a quad digital potentiometer IC manufactured by onsemi. It features four independent potentiometers, each with 256 taps and a total resistance of 100 kOhms. The device utilizes an I2C serial interface for control and includes non-volatile memory to retain wiper settings. Operating voltage ranges from 2.5 V to 6 V with a typical current consumption of 1 mA. It is housed in a 24-pin SOIC package and operates within a temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with 256-tap resolution per potentiometer
• Non-volatile memory retains wiper position after power loss
• I2C serial interface for digital control
• Linear taper with 100 kOhms nominal resistance

Digital Potentiometers Applications

• Audio volume and tone control circuits
• Programmable gain amplifier adjustments
• Voltage reference trimming
• Instrumentation calibration systems

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for obsolescence notices as the lifecycle status may indicate end-of-life conditions. Ensure packaging specifications match production requirements.

Digital Potentiometers Selection Notes

Select this component when multiple isolated digital potentiometer channels are required. The 100 kOhms resistance value suits moderate impedance applications. Verify that the I2C address configuration meets system bus constraints. Consider the SOIC-24 footprint for PCB layout compatibility.

Digital Potentiometers Part Context

This part belongs to the CAT5259 family of quad digital potentiometers. The 'WI' suffix indicates industrial temperature range and SOIC packaging. The '00' denotes the 100 kOhms resistance value. The '-T1' suffix specifies tape and reel packaging format for automated assembly.

Digital Potentiometers Replacement Considerations

Cross-reference with CAT5259 variants having different resistance values (e.g., CAT5259WI-01 for 10k, CAT5259WI-02 for 50k) if resistance adjustment is needed. Single-channel alternatives like CAT5241 offer fewer pots but similar interface characteristics.
