MAX6225BESA

Overview

The MAX6225BESA+ is a low-noise, precision voltage reference utilizing buried-zener technology. It provides a fixed output of 2.500V with an initial accuracy of ±0.12% and a maximum temperature coefficient of 7ppm/°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 3mA maximum and operates across a temperature range of -40°C to +85°C in an 8-pin SO package.

Feature Summary

• Buried-zener technology for lowest noise performance
• Excellent line and load regulation with low output impedance at high frequency
• Optional external trimming and noise reduction capabilities
• Stable operation for all capacitive loads

Applications

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

Procurement Notes

Verify the specific suffix 'B' indicates the ±0.12% accuracy grade and 7ppm/°C temperature coefficient variant. Confirm the 'E' suffix corresponds to the -40°C to +85°C operating range and SOIC package type. Ensure the '+' suffix denotes lead-free/RoHS compliance status as per manufacturer specifications before procurement.

Selection Notes

Select this component when high stability and low noise are required for precision measurement applications. The buried-zener architecture ensures superior long-term stability compared to bandgap references. Consider the trim pin availability if fine-tuning of the output voltage is necessary for specific system calibration requirements.

Part Context

This part belongs to the MAX6225/MAX6241/MAX6250 family of low-noise, precision voltage references. While sharing similar architectural features and pinouts, the MAX6225 specifically targets the 2.5V output requirement. Other family members provide different nominal voltages such as 4.096V or 5.000V.
