MAX6143BASA41+

Overview

The MAX6143BASA41+ is a high-precision series voltage reference with a fixed output of 4.096V, housed in an 8-pin SO package. It features a maximum temperature coefficient of 10ppm/°C and an initial accuracy of 0.1%. The device accepts input voltages from VOUT + 2V up to 40V, draws a maximum quiescent current of 650µA, and can source up to 30mA or sink 2mA. It includes a linear temperature sensor output and an active-low shutdown pin.

Feature Summary

• Integrated linear temperature transducer providing die temperature proportional voltage output
• Active-low shutdown capability for ultra-low power consumption
• Output voltage trimming via external resistive divider network
• Stable operation without requiring 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 0.1% accuracy class and 10ppm/°C temperature coefficient variant. Confirm the 'SA' designation corresponds to the standard 8-SOIC package. Ensure the '+' suffix confirms RoHS compliance status before finalizing procurement specifications.

Selection Notes

Select this component when a 4.096V reference with moderate precision (0.1%) is required alongside integrated temperature sensing capabilities. It is suitable for applications needing wide input voltage ranges and low standby power through shutdown mode, provided the higher noise and drift compared to the 'A' grade variants are acceptable.

Part Context

This part belongs to the MAX6143 family of high-precision voltage references manufactured by Analog Devices Inc./Maxim Integrated. The family offers various fixed output voltages and accuracy grades, utilizing proprietary curvature-correction circuits and laser-trimmed thin-film resistors for stability across the automotive temperature range.
