MC1403P1

Overview

The MC1403P1 is a series voltage reference integrated circuit manufactured by onsemi, housed in an 8-pin PDIP package. 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 draws a maximum supply current of 1.5mA. It supports a maximum output current of 10mA and features a temperature coefficient of 40ppm/°C. The component is rated for through-hole mounting and functions across a temperature range of -40°C to 85°C (TA).

Feature Summary

• Provides a stable 2.5V series reference voltage with high initial accuracy.
• Operates over a wide input voltage range up to 40V.
• Supports load currents up to 10mA with low quiescent current consumption.

Applications

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

Procurement Notes

Verify the specific suffix 'P1' corresponds to the PDIP-8 package and commercial temperature grade when sourcing. Confirm RoHS compliance status as historical data indicates non-compliance for this specific part number variant. Check manufacturer announcements for obsolescence notices or product change notifications affecting availability and specifications.

Selection Notes

Select this component when a fixed 2.5V reference is required in a through-hole design. Ensure the input voltage remains between 4.5V and 40V to maintain regulation. Consider the 40ppm/°C temperature coefficient for thermal stability requirements. Verify that the 10mA output current capability meets the load demands of the target application circuit.

Part Context

The MC1403B is part of onsemi's legacy voltage reference family, offering a simple two-terminal solution for precision applications. The MC1403P1 specifically denotes the DIP-8 packaging variant. This series serves as a cost-effective alternative to more complex adjustable references where a fixed voltage is sufficient.
