MAX6250BCSA+T

Overview

The MAX6250BCSA+T 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 5.0ppm/°C. The device operates within an input voltage range of 8V to 36V and draws a typical supply current of 3.0mA. It supports source and sink currents up to 15mA and features optional external trimming and noise reduction capabilities.

Feature Summary

• Buried-zener technology ensures extremely low noise performance for high-resolution applications.
• Offers excellent line and load regulation with low output impedance at high frequencies.
• Supports external trimming via the TRIM pin and wideband noise reduction via the NR pin.

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 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as indicated by the '+' designation in the part number. Ensure the operating environment remains within the specified commercial temperature range of 0°C to +70°C for this grade.

Selection Notes

Select this component for systems requiring a stable 5V reference with minimal drift. The buried-zener architecture is suitable for low-frequency noise-sensitive circuits. Consider the 8-pin SO package constraints for PCB layout. Verify that the required output current does not exceed the 15mA limit for both sourcing and sinking operations.

Part Context

This part belongs to the MAX6225/MAX6241/MAX6250 family of precision voltage references. While sharing similar internal architectures and pinouts, the MAX6250 variant is specifically configured for a 5.000V output, distinguishing it from the 2.5V and 4.096V options available in the series.

Replacement Considerations

Direct functional substitutes within the same family include MAX6250ACSA+T (lower tempco) or MAX6250AESA+T (extended temperature range). Cross-family replacements require verification of pin compatibility and electrical parameter alignment.

FAQ

How can the output noise be reduced?

Connect a 1μF capacitor between the NR pin and ground to augment wideband noise reduction.

Is the device stable with capacitive loads?

Yes, the MAX6250BCSA+T is stable with capacitive load values ranging from 0μF to 100μF across all load currents.
