MAX674ESA+T

Overview

The MAX674ESA+T is a precision voltage reference providing a fixed +10V output. It features an initial accuracy of ±0.15% and a temperature coefficient of 12 ppm/°C. The device operates within a supply voltage range up to 40V, with a maximum input voltage of 33V for regulation. Quiescent current is 1.4mA maximum. It includes short-circuit protection and offers an adjustment range of ±300mV via the trim terminal. Operating temperatures span from -40°C to +85°C.

Feature Summary

• Pretrimmed to +10V with ±0.15% initial accuracy
• Excellent temperature stability at 12ppm/°C
• Low noise performance of 20µVP-P
• Short-circuit protected design

Applications

• A/D Converters
• D/A Converters
• Digital Voltmeters
• Voltage Regulators
• Threshold Detectors

Procurement Notes

Verify the specific suffix 'ESA' confirms the narrow SOIC-8 package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status through official documentation. Ensure the ordering code matches the required pin configuration and thermal characteristics for your PCB layout.

Selection Notes

Select this component when a stable +10V reference is required for high-precision instrumentation. The narrow SO package suits space-constrained designs. Consider the 1.4mA quiescent current for power budgeting. Verify that the 12ppm/°C drift meets system calibration requirements over the full operating temperature range.
