MAX6143BASA25+

Overview

The MAX6143BASA25+ is a high-precision series voltage reference with a fixed output of 2.5V, housed in an 8-pin SO package. It features a maximum temperature coefficient of 10ppm/°C and initial accuracy of 0.1%. The device accepts input voltages from VOUT + 2V up to 40V, draws a maximum quiescent current of 650µA across the -40°C to +125°C operating range, and provides a linear temperature sensor output.

Feature Summary

• Integrated linear temperature transducer output proportional to die temperature
• Active-low shutdown capability for ultra-low power consumption
• Output voltage trimming via external resistive divider network
• Stable operation without requiring external output bypass capacitors

Applications

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

Procurement Notes

Verify the specific suffix 'B' indicates the 10ppm/°C temperature coefficient variant rather than the tighter 3ppm/°C 'A' grade. Confirm the 'SA' designation corresponds to the standard 8-SOIC package dimensions. Ensure the '+' suffix confirms compliance with RoHS3 standards as specified by the manufacturer documentation.

Selection Notes

Select this component when a 2.5V reference is required alongside integrated temperature sensing capabilities. The B-grade specification suits applications where 10ppm/°C drift is acceptable. Consider the TRIM pin utility if fine-tuning the output voltage beyond factory presets is necessary for system calibration.

Part Context

This part belongs to the MAX6143 family of low-noise, high-precision voltage references manufactured by Analog Devices Inc./Maxim Integrated. The family utilizes bandgap technology with laser-trimmed thin-film resistors to achieve excellent stability and low noise performance suitable for precision analog signal chains.
