MAX6250AESA+T

Overview

The MAX6250AESA+T is a low-noise, precision voltage reference utilizing buried-zener technology. It provides a fixed 5.000V output with ±0.02% initial accuracy and a maximum temperature coefficient of 3.0ppm/°C. The device operates within an input voltage range of 8V to 36V and draws a supply current of up to 3.3mA. It supports source and sink currents up to 15mA and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Buried-zener technology ensures extremely low noise performance for high-resolution applications.
• Features optional external trimming and noise reduction capabilities via dedicated pins.
• Maintains stability with capacitive loads ranging from 0μF to 100μF.

Applications

• High-Resolution Analog-to-Digital and Digital-to-Analog Converters
• High-Accuracy Reference Standard
• Digital Voltmeters

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and RoHS compliance status. Ensure the ordering code matches the required temperature grade and pin configuration. Confirm availability through authorized distributors as stock levels fluctuate. Cross-reference datasheet revisions to ensure compatibility with existing designs.

Selection Notes

Select this component when a stable 5V reference with low drift is required. Consider the buried-zener architecture for superior noise characteristics compared to bandgap references. Evaluate the need for external trimming if tighter tolerance than ±0.02% is necessary. Verify that the 8V minimum input voltage aligns with the system power supply constraints.

Part Context

This part belongs to the MAX6225/MAX6241/MAX6250 family of precision voltage references. While sharing similar internal architectures and features, each variant offers a distinct fixed output voltage: 2.5V, 4.096V, or 5.0V respectively. The MAX6250 specifically targets applications requiring a 5V precision rail.

Replacement Considerations

Direct substitutes include other parts within the MAX6225/MAX6241/MAX6250 series with matching output voltages and packages. Verify pinout compatibility and electrical specifications before substitution.
