SG1503Y

Overview

The SG1503Y is a three-terminal voltage reference IC manufactured by Microchip Technology. It provides a precise 2.5V output with trim/adjustable capabilities. The device is housed in an 8-pin ceramic dual in-line package (CDIP-8). It features a single output configuration designed for applications requiring stable voltage references.

Feature Summary

• Provides a fixed 2.5V output voltage
• Features adjustable voltage trimming capability
• Utilizes a robust ceramic dual in-line package

Applications

• Precision measurement systems
• Data acquisition circuits
• Instrumentation amplifiers

Procurement Notes

Verify the specific manufacturer designation, as historical data indicates production by Linfinity Microelectronics and Microsemi before Microchip acquisition. Confirm the package type matches the required CDIP-8 specification. Ensure the part number suffix aligns with the intended trimmable variant.

Selection Notes

Select this component when a highly stable 2.5V reference is required in a ruggedized environment. The ceramic DIP package offers superior thermal and mechanical stability compared to plastic variants. Consider the trimmable feature if tight initial tolerance calibration is necessary for the application.

Part Context

This component belongs to the family of precision voltage references used in analog signal processing. It serves as a foundational element for establishing accurate reference potentials in mixed-signal circuits. The design supports high reliability requirements typical of industrial and military-grade electronics.

Replacement Considerations

Cross-reference with SG1503Y/DESC and SG1503Y-DESC for equivalent functionality from Microchip or legacy manufacturers. Verify pinout compatibility and electrical specifications before substitution.
