MAX6225BESA+T

Overview

The MAX6225BESA+T is a buried-zener voltage reference providing a fixed 2.500V output in an 8-pin SO package. It operates within an extended temperature range of -40°C to +85°C and accepts input voltages from 8V to 36V. The device guarantees ±0.02% initial accuracy with a maximum temperature coefficient of 7ppm/°C. It supports continuous source and sink currents up to 15mA while consuming approximately 3mA of supply current.

Feature Summary

• Utilizes buried-zener technology for low-noise performance
• Features external trimming capability via the TRIM pin
• Supports optional noise reduction through the NR pin
• Maintains stability across all capacitive loads

Applications

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

Procurement Notes

Verify that the ordering suffix '+T' corresponds to the tape-and-reel packaging configuration as specified by Analog Devices. Confirm the component meets RoHS compliance standards required for your assembly process. Ensure the specific B-grade accuracy and E-grade temperature rating match your design requirements before finalizing procurement.

Selection Notes

Select this part when high precision and low noise are critical for data conversion applications. The buried-zener architecture provides superior long-term stability compared to bandgap references. Consider the available external trim and noise reduction pins if your system requires tighter tolerance or lower wideband noise than standard specifications allow.

Part Context

This component belongs to the MAX6225/MAX6241/MAX6250 family of low-noise, precision voltage references manufactured by Analog Devices. These devices share identical pinouts and core technologies but differ in their fixed output voltages and specific accuracy grades. The MAX6225 variant specifically targets applications requiring a stable 2.5V reference.

Replacement Considerations

Direct replacements include other variants within the MAX6225 series such as MAX6225AESA+ or MAX6225ACSA+, depending on the required temperature range and accuracy grade. Verify that any substitute maintains the same 8-pin SO package and electrical characteristics.
