Overview
The MC1403P1G 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 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 operation between -40°C and +85°C ambient temperature.
Feature Summary
- Provides a stable 2.5V series voltage reference 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
- Calibration equipment requiring stable voltage standards
Procurement Notes
Verify the specific suffix 'G' indicates RoHS compliance status, as some MC1403 variants are non-compliant. Confirm package type matches 8-PDIP requirements. Check obsolescence notices from onsemi, as this family has undergone discontinuation announcements. Ensure thermal management aligns with the specified operating temperature range during design integration.
Selection Notes
Select this component when a precise 2.5V reference is required for through-hole designs. Consider the 40ppm/°C temperature coefficient against application stability needs. Compare against SOIC variants like MC1403BD if surface mount space is limited. Verify input voltage constraints do not exceed the 40V maximum rating under all operating conditions.
Part Context
This part belongs to the MC1403 family of three-terminal series voltage references. It shares core electrical characteristics with other variants such as MC1403BP1 and MC1403BDR2, differing primarily in packaging and compliance markings. The family is designed for general-purpose precision applications requiring a stable reference voltage independent of supply fluctuations.
Replacement Considerations
Direct pin-compatible substitutes include MC1403BP1 and MC1403BDG, though RoHS compliance may vary. Cross-reference datasheets for exact temperature coefficient and tolerance specifications before substitution.
