MAX6250ACSA+

Overview

The MAX6250ACSA+ is a buried-zener voltage reference providing a fixed 5.000V output in an 8-pin SO package. It operates within an input voltage range of 8V to 36V and draws 3.3mA supply current. The device guarantees ±0.02% initial accuracy with a maximum temperature coefficient of 2ppm/°C. Noise performance includes 3µVp-p (0.1Hz to 10Hz) and 2.5µVrms (10Hz to 1kHz). It supports source and sink currents up to 15mA, features long-term stability of 20ppm/1000h, and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Utilizes buried-zener technology for low-noise precision
• Offers 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
• High-accuracy industrial process control
• Precision digital voltmeters
• Automated test equipment

Procurement Notes

Verify the specific suffix 'CSA+' indicates the 8-SOIC package and commercial temperature range. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the application requires the fixed 5V output variant rather than adjustable or other voltage options within the family. Check lead-free specifications against local regulatory requirements.

Selection Notes

Select this component when high precision and low noise are critical for 16-bit data conversion systems. The buried-zener architecture provides superior stability compared to bandgap references. Consider the 8-pin SO package constraints and verify that the 8V minimum input voltage aligns with the system power supply design.

Part Context

This part belongs to the MAX6225/MAX6241/MAX6250 series of low-noise, precision voltage references. While sharing identical electrical characteristics and pinouts, the MAX6250 is specifically configured for a 5.000V output. Other variants in the series provide 2.500V or 4.096V outputs using the same underlying technology and packaging options.

Replacement Considerations

Direct replacements include MAX6250AEPA+, MAX6250AESA+, and MAX6250ACPA+. Verify that alternative packages such as PDIP or CERDIP fit the physical layout. Ensure the selected substitute matches the required temperature range and accuracy grade.
