MAX6220ASA-4.1

Overview

The MAX6220ASA-4.1 is a low-noise, precision voltage reference featuring buried-zener technology. It provides a fixed output voltage of 4.096V with an initial accuracy of ±0.1% and a temperature coefficient of 2 ppm/°C. The device operates from a supply voltage up to 42V and draws a typical supply current of 3.5mA. It is housed in an 8-SOIC surface-mount package and supports an operating temperature range of -40°C to +125°C.

Feature Summary

• Utilizes buried-zener technology for superior noise performance
• Delivers high precision with ±0.1% initial accuracy
• Maintains stability across wide temperature variations

Applications

• High-resolution data acquisition systems
• Precision analog-to-digital converter references
• Medical instrumentation requiring stable voltage sources

Procurement Notes

Verify the specific suffix (e.g., + or -T) against the manufacturer's official datasheet to confirm lead-free status and tape-and-reel packaging configuration. Ensure the supplier source matches Analog Devices or Maxim Integrated specifications to avoid counterfeit components.

Selection Notes

Select this component when low noise and high precision are critical for signal integrity. The 4.096V output is suitable for driving ADCs directly. Consider the 8-SOIC package constraints for PCB layout and thermal management requirements within the specified industrial temperature range.

Part Context

This part belongs to the MAX6220 family of low-noise voltage references. It shares architectural similarities with the MAX6225 and MAX6241 but offers specific output voltage options including 2.5V, 4.096V, and 5V variants within the same series.

Replacement Considerations

Compatible substitutes include MAX6220ASA-2.5+ and MAX6220ASA-5.0+ for different reference voltages. Cross-reference with MAX6241BCPA for DIP package alternatives if pin compatibility allows.
