Overview
The MCP1501T-40E/RW is a buffered voltage reference from Microchip Technology offering a fixed output of 4.096 V with an initial accuracy of ±0.1%. It operates within a supply voltage range of 4.3 V to 5.5 V and maintains a maximum temperature coefficient of 50 ppm/°C across the -40°C to +125°C industrial temperature range. The device features a typical operating current of 140 μA, supports up to 20 mA load current, and utilizes an 8-WDFN package.
Feature Summary
- Provides high-precision buffered voltage output with low drift characteristics using chopper-based amplifiers.
- Capable of sourcing and sinking significant load currents for direct drive applications.
- Includes a digital shutdown pin for active power management control.
Applications
- Precision data acquisition systems
- High-resolution data converters
- Medical equipment applications
Procurement Notes
Verify the specific suffix 'RW' indicates reel packaging against official Microchip documentation. Confirm the 'E' grade meets required accuracy specifications. Ensure the WDFN-8 footprint matches PCB design constraints. Validate RoHS compliance status prior to integration.
Selection Notes
Select this variant when a stable 4.096 V reference is required in a compact surface-mount form factor. Consider the minimum input voltage requirement of 4.3 V relative to available supply rails. Evaluate thermal performance requirements given the exposed pad design for heat dissipation.
Part Context
This component belongs to the MCP1501 family of high-precision buffered voltage references. The family includes multiple voltage options and package types such as SOT-23, SOIC, and WDFN. The T suffix typically denotes tape and reel packaging, while RW specifies the specific reel configuration.
Replacement Considerations
Direct substitutes include other MCP1501 variants with identical 4.096 V output and compatible packages, such as MCP1501-40E/SN or MCP1501-40E/CHY, provided pinout and electrical parameters align with system requirements.
