MAX6350CSA+T

Overview

The MAX6350CSA+T is a buried-zener series voltage reference providing a fixed 5V output. It features an industry-standard pinout and supports external trimming for voltage adjustment. The device operates within an input voltage range of 8V to 36V and maintains stability across all capacitive loads from 0µF to 100µF. It offers ±0.02% initial accuracy with a maximum temperature coefficient of 1ppm/°C in the C-grade variant. The component draws approximately 3.3mA supply current and delivers up to 15mA source or sink load current.

Feature Summary

• Utilizes buried-zener technology for low-noise performance
• Provides optional noise reduction via NR pin
• Supports external voltage trimming through TRIM pin
• Maintains stability with any capacitive load

Applications

• High-resolution analog-to-digital converters
• Digital-to-analog converters
• Precision current sources
• High-accuracy industrial process control systems

Procurement Notes

Verify that the ordering suffix matches the required temperature grade, as the CSA designation indicates commercial range operation. Confirm package type requirements against the specific application constraints. Ensure compatibility with existing board layouts due to the industry-standard pin configuration. Cross-reference datasheet specifications for line and load regulation limits before finalizing procurement decisions.

Selection Notes

Select this component when high precision and low drift are critical for data conversion systems. Consider the buried-zener architecture for superior noise characteristics compared to bandgap references. Evaluate the need for external trimming if tighter tolerance than factory settings is required. Verify input voltage availability falls within the specified 8V to 36V operational window.

Part Context

This part belongs to the MAX6325/MAX6341/MAX6350 family of precision voltage references. While sharing identical pinouts and core technologies, each variant provides a different fixed output voltage. The MAX6350 specifically targets applications requiring a stable 5V reference. All members utilize low-power temperature compensation schemes without requiring heated references.

Replacement Considerations

Direct substitutes include other parts from the same family such as the MAX6325 or MAX6341, provided the output voltage difference is acceptable. Alternative packages like Plastic DIP (CPA) or CERDIP (MJA) offer the same functionality with different thermal and mechanical properties.
