MC1403DR2G

Overview

The MC1403DR2G is a series voltage reference integrated circuit manufactured by onsemi. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±1%. The device operates within an input voltage range of 4.5V to 40V and supports a maximum output current of 10mA. It features a temperature coefficient of 40ppm/°C and draws a supply current of 1.5mA. Packaged in an 8-SOIC surface-mount format, it functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Provides a stable 2.5V series reference voltage with high precision
• Operates across a wide input voltage range up to 40V
• Delivers up to 10mA load current capability
• Ensures thermal stability with a low temperature coefficient

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• Calibration circuits requiring stable DC voltage levels
• Battery-powered instrumentation systems

Procurement Notes

Verify the specific suffix DR2G corresponds to the SOIC-8 tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component meets RoHS compliance standards if environmental regulations apply to the target manufacturing facility. Ensure the operating environment remains within the specified commercial temperature limits to maintain the stated accuracy specifications.

Selection Notes

Select this component when a fixed 2.5V reference is required with tight initial tolerance. Consider the 40ppm/°C temperature drift against application requirements. Evaluate the 10mA output current capacity against the total load demand. Verify compatibility with the 8-SOIC footprint during PCB layout design.

Part Context

This part belongs to the MC1403 family of series voltage references from onsemi. It serves as a fundamental building block for power management and signal conditioning circuits. The DR2G designation indicates the specific surface-mount package and reel quantity configuration used for industrial distribution.

Replacement Considerations

Cross-reference with other MC1403 variants such as MC1403BD or MC1403BP1 for different package types. Verify pinout compatibility before substituting with generic 2.5V references. Check datasheets for differences in temperature coefficients and output current capabilities.
