MAX6143AASA10

Overview

The MAX6143AASA10 is a high-precision voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 10V with an initial accuracy of ±0.05% and a maximum temperature coefficient of 3ppm/°C. The device operates within an input voltage range of (VOUT + 2V) to +40V, drawing a typical supply current of 340µA. It features a low noise performance of 3.8µVP-P at the 2.5V output setting and can source up to 30mA or sink 2mA of load current. The component includes a temperature sensor output and a trim input for fine adjustment.

Feature Summary

• Proprietary curvature-correction circuit ensures excellent temperature stability
• Integrated temperature sensor output proportional to die temperature
• Trim input allows fine adjustment via resistive-divider network
• Stable without output bypass capacitor, supporting capacitive loads up to 100µF

Applications

• High-resolution A/D converter references
• D/A converter references
• Temperature-sensing applications

Procurement Notes

Verify the specific suffix 'AASA10' against official Analog Devices documentation to confirm the 10V output variant and SOIC-8 package configuration. Ensure compatibility with the required input voltage range and thermal management specifications for your application environment.

Selection Notes

Select this component when a stable 10V reference is required alongside integrated temperature sensing capabilities. Consider the low power consumption and shutdown feature for battery-operated systems. Verify that the 30mA sourcing capability meets the load requirements of the connected circuitry.
