MAX6225BCSA+T

Overview

The MAX6225BCSA+T 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 5.0 ppm/°C. The device operates within an input voltage range of 8V to 36V and supports source/sink currents up to 15mA. It features a typical supply current of 3.0mA and delivers 1.5µVp-p noise in the 0.1Hz to 10Hz bandwidth. Packaged in an 8-pin SOIC, it functions reliably across a temperature range of 0°C to +70°C.

Feature Summary

• Buried-zener technology ensures extremely low noise performance for high-resolution applications.
• Offers optional external trimming and noise reduction capabilities via dedicated pins.
• Capable of sourcing and sinking load currents up to 15mA with excellent regulation.
• Stable for all capacitive loads ranging from 0µF to 100µF.

Applications

• High-Resolution Analog-to-Digital and Digital-to-Analog Converters
• High-Accuracy Reference Standard
• Digital Voltmeters
• Precision Current Sources

Procurement Notes

Verify the specific suffix 'CSA' confirms the 8-pin SO package and 'B' grade indicates the 5.0 ppm/°C temperature coefficient limit. Ensure the '+T' designation aligns with reel packaging requirements if applicable. Confirm RoHS compliance status matches project specifications. Validate that the operating temperature range of 0°C to +70°C meets environmental constraints before finalizing procurement.

Selection Notes

Select this component when a 2.5V reference is required with moderate temperature stability (5ppm/°C). It is suitable for systems needing ±15mA drive capability without active cooling. Consider the MAX6225ACSA+T variant if tighter accuracy (±0.04%) and lower drift (2ppm/°C) are necessary. Evaluate power consumption constraints against the 3mA supply current requirement.

Part Context

Part of the MAX6225/MAX6241/MAX6250 family of low-noise precision references. The MAX6225 specifically targets the 2.5V output segment, while siblings provide 4.096V and 5.000V options. All share identical pinouts and feature sets, differing primarily in factory-set output voltages and specific accuracy grades.

Replacement Considerations

Direct replacement: MAX6225BCSA+ (non-tape/reel version).
