MCP1501-40E/SN

Overview

The MCP1501-40E/SN is a buffered voltage reference from Microchip Technology, providing a nominal 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 operating range. The device features low typical operating current of 140 μA and can source or sink up to 20 mA of load current.

Feature Summary

• High precision band gap architecture utilizing chopper-based amplifiers for reduced drift
• Buffered output capable of sourcing and sinking significant load currents
• Integrated shutdown pin for digital control of power consumption

Applications

• Precision data acquisition systems
• High-resolution data converters
• Medical equipment applications
• Industrial controls
• Battery-powered devices

Procurement Notes

Verify the specific suffix 'SN' corresponds to the SOIC-8 package configuration required for your design. Confirm that the input supply voltage meets the minimum requirement of 4.3 V for stable operation at the 4.096 V output level. Ensure thermal management aligns with the specified junction-to-ambient resistance for the chosen PCB layout.

Selection Notes

Select this component when a stable 4.096 V reference is needed with high initial accuracy. Consider the SOIC-8 package if surface-mount assembly in standard footprints is preferred over smaller alternatives. Evaluate the 50 ppm/°C temperature coefficient against system drift requirements across the full industrial temperature range.

Part Context

This part belongs to the MCP1501 family of high-precision buffered voltage references. The family offers multiple fixed voltage options ranging from 1.024 V to 5.000 V. Variants are available in different packages including SOT-23-6, SOIC-8, and WDFN-8 to suit various space and thermal constraints.

Replacement Considerations

The MCP1501-40E/SNTR is the tape-and-reel version of this same component. Other voltage variants within the MCP1501 series share identical pinouts and electrical characteristics except for the output voltage value.
