MAX6250AEPA+

Overview

The MAX6250AEPA+ 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 3ppm/°C. The device operates within an input voltage range of 8V to 36V and supports source/sink currents up to 15mA. It features a supply current of approximately 3.3mA and operates across a temperature range of -40°C to +85°C. Packaged in an 8-pin Plastic DIP, it offers excellent line and load regulation suitable for high-resolution data-conversion systems.

Feature Summary

• Buried-zener technology ensures lowest noise performance
• Excellent transient response and stability for all capacitive loads
• Optional external trimming and noise reduction capabilities

Applications

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

Procurement Notes

Verify the specific suffix 'EPA+' corresponds to the required -40°C to +85°C extended temperature range and 8-pin PDIP package configuration. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the design accommodates the specified 8V to 36V input voltage requirements and thermal dissipation limits for the plastic DIP package during operation.

Selection Notes

Select this component when a fixed 5V precision reference is required with strict low-noise specifications. The buried-zener architecture is optimal for applications demanding minimal flicker noise. Consider the ±0.02% initial accuracy and 3ppm/°C temperature coefficient for high-precision measurement systems. Verify that the 15mA output current capability meets the load requirements without exceeding power dissipation limits.

Part Context

This part belongs to the MAX6225/MAX6241/MAX6250 family of low-noise, precision voltage references. While sharing similar internal architectures and feature sets, the MAX6250 variant is specifically configured for a 5.000V output, distinguishing it from the 2.5V and 4.096V options within the same series.

FAQ

How can wideband noise be reduced on the MAX6250AEPA+?

A 1μF capacitor can be added to the NR (Noise Reduction) pin to augment wideband noise reduction. Larger capacitance values do not significantly improve noise performance.

Is the MAX6250AEPA+ stable with capacitive loads?

Yes, the device is stable with capacitive load values ranging from 0μF to 100μF for all values of load current.
