Digital Potentiometers datasheet and documents for CAT5261YI50
Digital Potentiometers Overview
The CAT5261YI50 is a dual-channel digital potentiometer IC manufactured by onsemi. It features two independent potentiometers, each with 256 tap positions and a resistance value of 50 kOhms. The device utilizes a non-volatile memory architecture to retain wiper settings during power-down events. Control is managed via an SPI digital interface. Operating specifications include a supply voltage range of 2.5 V to 6 V and a temperature range from -40°C to +85°C. The component is housed in a 24-TSSOP surface-mount package.
Digital Potentiometers Feature Summary
- Dual-channel configuration with 256-tap resolution per potentiometer
- Non-volatile memory retains wiper position after power loss
- SPI serial interface for digital control
- Linear taper with 50 kOhm nominal resistance
Digital Potentiometers Applications
- Automated gain control in signal processing circuits
- Calibration of sensor measurement systems
- Voltage reference adjustment in instrumentation
Digital Potentiometers Procurement Notes
Verify the specific suffix 'YI50' against official onsemi documentation to confirm pinout compatibility and electrical tolerances. Confirm availability status as distribution channels may list obsolete or end-of-life inventory. Ensure the source provides valid RoHS compliance data and original manufacturer traceability before procurement.
Digital Potentiometers Selection Notes
Select this component when a dual-channel solution with non-volatile storage is required. Verify that the 50 kOhm resistance value aligns with the target circuit impedance requirements. Ensure the design supports the 2.5 V to 6 V operating voltage range and utilizes an SPI-compatible controller for interface connectivity.
Digital Potentiometers Part Context
This part belongs to the CAT5261 family of digital potentiometers. The 'YI' designation typically indicates the industrial temperature grade and TSSOP-24 packaging. The '50' suffix specifies the 50 kOhm resistance value. This distinguishes it from other variants such as the CAT5261WI-00 which offers 100 kOhm resistance.
Digital Potentiometers Replacement Considerations
Direct replacements within the same family include CAT5261YI-00 (100 kOhm) if resistance scaling is acceptable. Cross-manufacturer equivalents require verification of SPI command sets and non-volatile memory behavior.
