MC1403BP1G

Overview

The MC1403BP1G 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 draws a supply current of 1.5mA. It features a temperature coefficient of 40ppm/°C and supports a maximum output current of 10mA. The component is housed in an 8-PDIP package with a pin spacing of 7.62mm (0.300 inches). It is designed for through-hole mounting and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides a stable, fixed 2.5V reference voltage with high precision accuracy.
• Operates over a wide input voltage range up to 40V for flexible power supply integration.
• Ensures thermal stability with a defined temperature coefficient for consistent performance.

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• Battery-powered measurement instrumentation
• Portable electronic devices requiring stable bias voltages

Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance status compared to the non-G variant. Confirm package dimensions match the 8-PDIP specification. Check current availability as the base part may have discontinuation notices. Ensure the supplier provides official datasheets for electrical parameter validation before procurement.

Selection Notes

Select this component when a fixed 2.5V reference is required with low quiescent current consumption. The wide input voltage range allows operation from various supply rails without additional regulation. Consider the through-hole package for prototyping or applications requiring mechanical robustness. Verify that the ±1% tolerance meets the system's accuracy requirements.

Part Context

This part belongs to the MC1403B family of series voltage references. It shares core electrical characteristics with variants such as MC1403BD and MC1403BP1, differing primarily in packaging and compliance markings. The family is designed for general-purpose voltage referencing in mixed-signal circuits.

Replacement Considerations

Direct substitutes include MC1403BP1 and MC1403BD. Verify pin compatibility and ensure the replacement meets the same 2.5V output and ±1% tolerance specifications. Check if RoHS compliance is mandatory for the target application.
