Overview
The MAX674ESA+ is a precision voltage reference providing a pretrimmed +10V output with ±0.15% initial accuracy. It features an excellent temperature stability of 12ppm/°C and low noise performance of 20µVP-P. The device operates within a -40°C to +85°C temperature range and is housed in an 8-pin narrow SO package. Electrical characteristics include a maximum quiescent supply current of 1.4mA, line regulation of 0.01%/V, and load regulation of 0.002%/mA. It incorporates short-circuit protection and allows for output adjustment via a dedicated trim terminal.

Procurement Notes
Verify the specific suffix 'ESA+' against official Maxim Integrated documentation to confirm the narrow SOIC package and industrial temperature range (-40°C to +85°C). Ensure compatibility with existing PCB footprints for 8-pin narrow SO packages. Cross-reference datasheet revisions to confirm pinout consistency and electrical specifications match the intended application requirements.
Selection Notes
Select this component when a stable +10V reference is required for high-precision analog circuits. The narrow SO package suits space-constrained designs. Consider the 12ppm/°C temperature coefficient for applications requiring minimal drift over wide temperature ranges. Verify that the 1.4mA maximum supply current aligns with system power budget constraints.
Part Context
The MAX674 series includes variants like the MAX674CPA and MAX674EPA, differing primarily in operating temperature ranges and packaging. The MAX674ESA+ specifically denotes the industrial grade version in a narrow SO package. This part belongs to a family of precision references designed for applications demanding high accuracy and stability without external trimming components.
Replacement Considerations
The datasheet notes pin-for-pin compatibility with REF01. Verify if alternative sources offer equivalent electrical specifications and package dimensions before substitution.
