Overview
The MC1403BD 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 10 mA. The component is housed in an 8-SOIC surface-mount package and functions reliably across a working temperature range of -40°C to 85°C.
Feature Summary
- Provides a stable, fixed 2.5V series voltage reference output.
- Operates over a wide input voltage range up to 40V.
- Delivers high precision with a ±1% initial accuracy tolerance.
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 'BD' confirms the SOIC-8 package and lead finish. Confirm RoHS compliance status as some variants may be non-compliant. Check for obsolescence notices or PCNs affecting availability. Ensure the operating temperature range meets system requirements.
Selection Notes
Select this part when a low-cost, fixed 2.5V reference is required in a surface-mount format. Compare against the MC1403BP1 if through-hole packaging is preferred. Consider the 40ppm/°C temperature coefficient for thermal stability needs. Verify input voltage constraints do not exceed the 40V maximum rating.
Part Context
This component belongs to the MC1403B family of voltage references. It shares core electrical specifications with other suffixes like BDG and BDR2, differing primarily in package type. The MC1403B series is designed for general-purpose applications requiring a reliable, low-drift voltage source.
Replacement Considerations
The MC1403BDG serves as a pin-compatible alternative in the same SOIC-8 footprint. Cross-reference datasheets to confirm identical pinout and electrical characteristics before substitution.
