MAX6143BASA10+

Overview

The MAX6143BASA10+ is a high-precision voltage reference with an integrated temperature sensor, manufactured by Analog Devices. It provides a fixed +10V output with an initial accuracy of ±0.1% and a maximum temperature coefficient of 10ppm/°C. The device operates from input voltages ranging from VOUT + 2V up to +40V, drawing a typical supply current of 340µA. It features a low-power shutdown mode reducing current to 0.01µA, a TRIM pin for fine adjustment, and a TEMP pin providing a linear voltage proportional to die temperature. Packaged in an 8-pin SOIC, it functions reliably across the automotive temperature range of -40°C to +125°C.

Feature Summary

• Integrated linear temperature transducer output proportional to die temperature
• Active-low shutdown capability for ultra-low power consumption
• Resistive-divider trim input for fine output voltage adjustment
• 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 'B' indicates the 0.1% initial accuracy and 10ppm/°C temperature coefficient variant. Confirm the 'SA' designation corresponds to the 8-pin SO package. Ensure the '+10' suffix matches the required +10V fixed output voltage. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity and revision status before procurement.

Selection Notes

Select this component when a stable +10V reference is required alongside on-chip temperature monitoring capabilities. It is suitable for applications demanding tight initial accuracy and moderate temperature stability within the automotive operating range. Consider the TRIM functionality if precise calibration beyond factory settings is necessary. Evaluate the quiescent current and shutdown requirements against system power budgets.

Part Context

This device belongs to the MAX6143 family of high-precision voltage references featuring proprietary curvature-correction circuits. The family offers various fixed output voltages including 2.5V, 3.3V, 4.096V, 5.0V, and 10V. Variants are distinguished by accuracy grades (A for 0.06%, B for 0.1%) and temperature coefficients. All variants share the same 8-pin SO package and core architecture.
