MAX6250AESA

Overview

The MAX6250AESA+ is a low-noise, precision voltage reference featuring buried-zener technology. It provides a fixed 5.000V output with ±0.02% initial accuracy and a maximum temperature coefficient of 3.0ppm/°C in the extended industrial range. The device operates on an input voltage of 8V to 36V, drawing approximately 3.0mA supply current. It supports source and sink currents up to 15mA and offers optional external trimming and noise reduction capabilities.

Feature Summary

• Utilizes buried-zener technology for extremely low noise performance
• Provides excellent initial accuracy and low temperature drift
• Supports bidirectional load regulation for both sourcing and sinking currents
• Features industry-standard pinout with optional external trim and noise reduction

Applications

• High-resolution analog-to-digital converters
• Digital-to-analog converters
• High-accuracy industrial process control systems
• Precision current sources

Procurement Notes

Verify that the ordering suffix matches the required temperature range and package type. Confirm RoHS compliance status if lead-free components are mandatory for the assembly process. Ensure the specific part number variant aligns with the design's electrical requirements before procurement.

Selection Notes

Select this component when high stability and low noise are critical for data conversion accuracy. Consider the extended temperature range (-40°C to +85°C) for industrial environments. Evaluate the need for external trimming or noise reduction capacitors based on system sensitivity requirements.

Part Context

This device belongs to the MAX6225/MAX6241/MAX6250 family of precision voltage references. While sharing similar architecture and features, each model offers a distinct fixed output voltage: 2.5V, 4.096V, and 5.0V respectively. They share common characteristics such as low power consumption and robust transient response.

Replacement Considerations

Direct replacements within the same family include MAX6250ACSA+ (commercial grade) or MAX6250AEPA+ (DIP package). Verify temperature range and package compatibility when substituting.
