MAX6143AASA50+

Overview

The MAX6143AASA50+ is a high-precision voltage reference providing a fixed 5.0V output with ±0.06% initial accuracy and a maximum temperature coefficient of 3ppm/°C. It operates from an input voltage range of (VOUT + 2V) to 40V, drawing 340µA of supply current while sourcing up to 30mA. The device includes a linear temperature sensor output proportional to die temperature and features an active-low shutdown pin that reduces current to 0.01µA. It requires no external output capacitor for stability.

Feature Summary

• Proprietary curvature-correction circuit ensures low temperature drift
• Integrated linear temperature transducer output
• Active-low shutdown capability for ultra-low power consumption
• Stable without external output bypass capacitors

Applications

• High-resolution A/D converters
• D/A converters
• Threshold detectors
• Digital voltmeters

Procurement Notes

Verify the specific suffix 'A' indicates the 0.06% accuracy grade and 'S' denotes the SOIC package. Confirm the '+'' signifies lead-free compliance. Ensure the ordering code matches the required 5.0V preset output. Cross-reference the manufacturer's latest documentation for any potential revisions or obsolescence notices before finalizing procurement specifications.

Selection Notes

Select this component when precise 5V referencing is required alongside integrated temperature sensing capabilities. The low noise profile makes it suitable for sensitive analog signal chains. Consider the TRIM pin functionality if fine-tuning the output voltage beyond factory presets is necessary for specific calibration requirements in the target application design.

Part Context

This part belongs to the MAX6143 family of high-precision voltage references manufactured by Analog Devices / Maxim Integrated. The series utilizes bandgap technology and laser-trimmed thin-film resistors to achieve superior accuracy. Other variants in the family offer different fixed output voltages such as 2.5V, 3.3V, and 10V, along with alternative accuracy grades like the MAX6143B series.
