MAX6225BEPA

Overview

The MAX6225BEPA+ is a low-noise, precision voltage reference featuring buried-zener technology. It provides a fixed output of 2.500V with an initial accuracy of ±0.02% and a maximum temperature coefficient of 7ppm/°C. The device operates within an extended temperature range of -40°C to +85°C in an 8-pin Plastic DIP package. It supports input voltages from 8V to 36V and guarantees load regulation for source and sink currents up to 15mA. Supply current is typically 2.7mA.

Feature Summary

• Utilizes buried-zener technology for minimal noise performance
• Offers optional external trimming and noise reduction capabilities
• Maintains stability across all capacitive loads

Applications

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

Procurement Notes

Verify the specific suffix 'E' indicates the -40°C to +85°C operating range and 'P' denotes the Plastic DIP package. Confirm RoHS compliance via the '+' suffix. Ensure the required temperature coefficient does not exceed the 7ppm/°C maximum specified for this grade. Cross-reference pinouts against the datasheet to confirm compatibility with existing layouts.

Selection Notes

Select this component when a fixed 2.5V reference is required with high precision. The BEPA variant suits applications needing extended temperature operation compared to commercial grades. Consider the 8-pin DIP form factor for through-hole assembly requirements. Evaluate if the 15mA drive capability meets the system's load demands.

Part Context

This part belongs to the MAX6225/MAX6241/MAX6250 family of low-noise precision voltage references. While the MAX6241 outputs 4.096V and the MAX6250 outputs 5.000V, the MAX6225 is specifically configured for a 2.500V output. All members share similar architectural features including buried-zener technology and industry-standard pinouts.
