MAX874ESA+

Overview

The MAX874ESA+ is a precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 4.096V with an initial accuracy of 0.1%. The device operates within an input voltage range of 2.5V to 36V and delivers a maximum output current of 400 µA. Designed for surface-mount applications, it is housed in an 8-SOIC package. The component functions effectively across a temperature range of -40°C to +85°C, ensuring stable performance in various electronic circuits requiring high-precision voltage regulation.

Feature Summary

• Provides a precise fixed output voltage of 4.096V
• Features low drift characteristics for stable operation
• Includes internal bandgap reference circuitry

Applications

• Precision analog-to-digital converter (ADC) references
• Data acquisition systems
• Instrumentation amplifiers
• High-resolution measurement equipment

Procurement Notes

Verify the specific suffix 'ESA+' to confirm the SOIC-8 package and lead-free RoHS compliance status. Confirm that the 4.096V output variant matches the design requirement, as other voltages may exist in the family. Check current availability status as distribution channels may vary for discontinued or limited-stock items. Ensure thermal management aligns with the specified operating temperature range during integration.

Selection Notes

Select this component when a highly accurate, low-drift voltage reference is required for sensitive analog circuits. The 4.096V output is suitable for driving ADCs that require precise reference inputs. Consider the 400 µA output current limit when designing load requirements. The 8-SOIC package offers a compact solution for space-constrained PCB layouts compared to larger through-hole alternatives.

Part Context

The MAX874 belongs to Maxim's family of precision voltage references, designed to replace older, less accurate components. It utilizes a bandgap architecture to maintain stability over temperature and time. This specific part number denotes the fixed 4.096V version in a surface-mount package, distinguishing it from adjustable variants or different output voltages within the same product line.

Replacement Considerations

Consider the MAX874EAI+ for alternative packaging options if available. Verify compatibility with existing board footprints before substituting with generic precision references.
