CAT5115YI-50-G

Digital Potentiometers Overview

The CAT5115YI-50-G is a single-channel digital potentiometer manufactured by onsemi. It features 32 tap positions with a linear taper and a nominal resistance of 50 kOhms. The device operates on a single supply voltage ranging from 2.5 V to 6.0 V, with a typical operating current of 100 uA. It utilizes a serial up/down interface for control and employs non-volatile memory to retain the wiper setting upon power loss. The component is housed in an 8-pin TSSOP surface-mount package and supports an industrial temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• Serial Up/Down control interface requiring minimal pins
• Single supply operation from 2.5 V to 6.0 V
• Linear taper with 32 discrete resistance steps

Digital Potentiometers Applications

• Automated product calibration
• Remote control adjustments
• Offset, gain, and zero control circuits
• Tamper-proof calibration systems

Digital Potentiometers Procurement Notes

Verify the specific suffix 'YI' against the official datasheet to confirm the package type (TSSOP) and temperature grade. Confirm RoHS compliance status through the manufacturer's current documentation. Check for end-of-life notifications or obsolescence warnings prior to finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this component when non-volatile storage is required to maintain resistance settings without continuous power. Ensure the 50 kOhm resistance value matches the circuit requirements. Verify that the serial interface timing aligns with the host microcontroller capabilities. Consider the TSSOP-8 package dimensions for PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the CAT5115 family of 32-tap digitally programmable potentiometers. Variants within the series differ primarily in resistance values (10k, 50k, 100k), package types (PDIP, SOIC, TSSOP, MSOP), and memory volatility. The YI suffix specifically denotes the TSSOP package variant.

Digital Potentiometers Replacement Considerations

Cross-reference with other CAT5115 variants such as CAT5115VI-50-G or CAT5115ZI-50-G if package compatibility allows. Verify pinout and electrical specifications match exactly before substituting.
