MAX6350EPA+

Overview

The MAX6350EPA+ is a buried-zener series voltage reference providing a fixed 5V output. It operates within an input voltage range of 8V to 36V and supports ±15mA source/sink currents. The device features a maximum temperature coefficient of 1.5ppm/°C and initial accuracy of ±0.02%. Electrical characteristics include a supply current of 3.3mA, noise of 3µVp-p (0.1Hz to 10Hz), and long-term stability of 35ppm/1000hr. It functions in temperatures from -40°C to +85°C.

Feature Summary

• Utilizes buried-zener technology for low-noise performance
• Features optional external trimming and noise reduction capabilities
• Stable with all capacitive loads up to 100µF

Applications

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

Procurement Notes

Verify the specific suffix 'EPA' corresponds to the -40°C to +85°C operating range and 8-pin Plastic DIP package. Confirm RoHS compliance status as indicated in the ordering information. Ensure the component matches the manufacturer's datasheet specifications before integration into designs requiring high precision.

Selection Notes

Select this component when a stable 5V reference is required for high-resolution data conversion systems. The buried-zener architecture ensures superior noise performance compared to bandgap references. Consider the ±15mA load capability and low output impedance for driving demanding analog circuits without significant regulation loss.

Part Context

This part belongs to the MAX6325/MAX6341/MAX6350 family of ultra-low noise voltage references. While sharing identical pinouts and core technologies, the MAX6350 variant is specifically configured for a 5V output. Other family members provide 2.5V or 4.096V outputs, allowing designers to maintain consistent board layouts across different voltage requirements.
