MAX6241ACSA+T

Overview

The MAX6241ACSA+T is a buried-zener precision voltage reference providing a fixed 4.096V output in an 8-pin SO package. It operates within a 0°C to +70°C temperature range with a maximum temperature coefficient of 2.0ppm/°C and ±0.02% initial accuracy. The device supports input voltages from 8V to 36V, draws approximately 2.9mA supply current, and delivers up to 15mA source/sink current. It features low noise performance and optional external trimming capabilities.

Feature Summary

• Utilizes buried-zener technology for superior noise reduction and stability
• Offers optional external voltage trimming via the TRIM pin
• Capable of sourcing and sinking load currents up to 15mA
• Maintains stability across all capacitive loads

Applications

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

Procurement Notes

Verify that the ordering suffix 'T' indicates tape-and-reel packaging rather than tube packaging when placing orders. Confirm the specific 'A' grade designation matches the required temperature coefficient and accuracy specifications for your application environment. Ensure compatibility with standard surface-mount assembly processes for the 8-SO package format.

Selection Notes

Select this component for applications requiring high precision and low noise without the power consumption of heated references. The buried-zener architecture provides excellent long-term stability compared to bandgap alternatives. Consider the 8-SO package constraints if space is limited, and utilize the NR pin for additional wideband noise filtering if necessary.

Part Context

This part belongs to the MAX6225/MAX6241/MAX6250 family of low-noise precision voltage references. While sharing identical pinouts and core technologies, the MAX6241 is distinguished by its fixed 4.096V output voltage, whereas other family members provide 2.5V or 5.0V outputs. All variants share similar electrical characteristics regarding line regulation and load regulation.

Replacement Considerations

Direct replacements include MAX6241ACPA+, MAX6241AEPA+, and MAX6241AESA+. Verify that alternative packages meet thermal dissipation requirements and that temperature ranges align with system operating conditions.
