MAX876AESA+TG002

Overview

The MAX876AESA+ is a precision voltage reference providing a fixed +10.0V output in an 8-pin SO package. It features a maximum temperature coefficient of 7ppm/°C and initial accuracy of ±0.03%. The device operates with a supply voltage range of +4.5V to +18V, drawing a typical quiescent current of 320µA. It sources up to 10mA and sinks up to 2mA, with low noise characteristics suitable for high-resolution data acquisition systems.

Feature Summary

• Provides a stable +10V reference with low drift and high initial accuracy
• Includes a dedicated TEMP pin for temperature-proportional voltage output
• Features a TRIM pin allowing output voltage adjustment via external potentiometer
• Offers short-circuit protection and stability with capacitive loads up to 100µF

Applications

• 12-bit ADCs and DACs
• Digital Multimeters
• Portable Data-Acquisition Systems
• Low-Power Test Equipment

Procurement Notes

Verify the specific suffix 'TG002' against official manufacturer documentation, as standard datasheets typically list 'E' (SOIC) or 'C' (TSSOP) package codes. Confirm RoHS compliance status and lead-free designation associated with the '+' suffix. Ensure the ordering code matches the exact package type and temperature range specifications required for your design.

Selection Notes

Select this component when a precise +10V reference is required with minimal temperature drift. It is suitable for applications needing low power consumption and high accuracy. Consider the available trim capability if fine-tuning is necessary. Verify that the input voltage range and load current requirements fall within the specified operational limits for optimal performance.

Part Context

This part belongs to the MAX873/MAX875/MAX876 family of low-power, low-drift precision voltage references. While the MAX873 provides +2.5V and the MAX875 provides +5V, the MAX876 specifically delivers a +10V output. All variants share similar architectural features, including curvature-correction circuits and laser-trimmed resistors for enhanced stability.

Replacement Considerations

Direct functional substitutes within the same family include MAX873AESA+ and MAX875AESA+, though their output voltages differ. Cross-family replacements should be evaluated based on output voltage, accuracy, and package compatibility.
