MAX6250BESA

Overview

The MAX6250BESA+ is a buried-zener voltage reference providing a fixed 5.000V output with ±0.02% initial accuracy and a maximum temperature coefficient of 7ppm/°C in the -40°C to +85°C range. It operates on an 8V to 36V input, draws 3.3mA supply current, and delivers up to 15mA source/sink current. The device features low noise (3µVp-p at 0.1Hz-10Hz), optional external trimming via the TRIM pin, and wideband noise reduction through the NR pin.

Feature Summary

• Buried-zener technology for ultra-low noise performance
• External trim capability for precise voltage adjustment
• Stable operation with capacitive loads up to 100µF
• Industry-standard pinout configuration

Applications

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

Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) and 'SA' denotes the SOIC package. Confirm RoHS compliance status based on the '+' designation. Ensure the required operating temperature aligns with the component's rated range before finalizing procurement specifications.

Selection Notes

Select this part when high precision and low noise are critical for 5V applications. Consider the MAX6250AESA+ if a tighter temperature coefficient is needed within the commercial range. Evaluate the MAX6250BEPA+ if a plastic DIP package is preferred over surface mount options.

Part Context

Part of the MAX6225/MAX6241/MAX6250 family offering 2.5V, 4.096V, and 5V outputs respectively. Designed for high-resolution data conversion systems up to 16 bits. Utilizes CMOS processing for low power consumption while maintaining laboratory-standard stability without requiring heated references.
