MAX6175AASA+T

Overview

The MAX6175AASA+T is a high-precision voltage reference providing a preset +5.0V output with ±0.06% initial accuracy and a maximum temperature coefficient of 3ppm/°C over the -40°C to +125°C range. It accepts input voltages from (VOUT + 2V) up to +40V, draws 320μA typical supply current, sources 30mA, and sinks 2mA. The device includes a linear temperature sensor output proportional to die temperature and a TRIM pin for fine adjustment via a resistive divider.

Feature Summary

• Proprietary curvature-correction circuit and laser-trimmed thin-film resistors ensure low noise and excellent stability.
• Integrated TEMP pin provides a voltage output linearly proportional to the internal die temperature.
• TRIM pin allows precise output voltage adjustment using an external resistive divider network.
• Inherent stability without requiring an output bypass capacitor, supporting capacitive loads up to 100μF.

Applications

• High-resolution Analog-to-Digital Converters (ADCs)
• Digital Voltmeters
• Automotive sensing systems
• Threshold detectors

Procurement Notes

Verify the specific suffix 'AASA' matches the required package type and temperature grade. Confirm that the '+T' designation aligns with the intended reel or cut tape packaging requirements for your assembly process. Ensure the ordering code corresponds to the exact +5.0V variant within the MAX617x family.

Selection Notes

Select this component when a stable +5.0V reference is needed alongside integrated temperature monitoring capabilities. The wide input voltage range accommodates various supply rails, while the low quiescent current supports power-sensitive designs. Verify that the 30mA sourcing capability meets the load requirements of the downstream circuitry.

Part Context

This part belongs to the MAX6173–MAX6177 series of high-precision voltage references manufactured by Analog Devices / Maxim Integrated. The series shares common features such as band-gap technology, short-circuit protection, and automotive-grade operating temperatures, differentiated primarily by their factory-preset output voltages ranging from +2.5V to +10V.

Replacement Considerations

Other members of the MAX6173–MAX6177 family offer identical functionality with different preset output voltages (+2.5V, +3.3V, +4.096V, +10V). Direct substitutes must match the +5.0V output specification and the SO-8 package configuration.
