MC1403BDR2

Overview

The MC1403BDR2 is a series voltage reference integrated circuit manufactured by onsemi. It provides a fixed output voltage of 2.5V with a tolerance of ±1%. The device operates within an input voltage range of 4.5V to 40V and delivers a maximum output current of 10 mA. It features a temperature coefficient of 40 ppm/°C and is housed in an 8-SOIC surface-mount package.

Feature Summary

• Provides a stable 2.5V series voltage reference output
• Operates over a wide input voltage range up to 40V
• Includes internal protection against short circuits and thermal overload

Applications

• Precision analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage sources
• Battery-powered measurement instrumentation

Procurement Notes

Verify the specific suffix 'R2' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure the component meets RoHS compliance requirements for the intended application environment. Cross-reference the part number with the latest onsemi documentation to confirm availability status and any recent manufacturing changes.

Selection Notes

Select this component when a low-cost, fixed 2.5V reference is required for general-purpose applications. Consider the ±1% tolerance and 40 ppm/°C temperature coefficient against stricter precision requirements. Evaluate the 8-SOIC package dimensions for compatibility with the target PCB layout constraints.
