MAX6175BASA+T

Overview

The MAX6175BASA+T is a high-precision series voltage reference providing a fixed +5.0V output with ±0.1% initial accuracy and a maximum temperature coefficient of 3ppm/°C. It operates from an input voltage range of 7.0V to 40V, drawing a typical supply current of 320μA. The device sources up to 30mA and sinks up to 2mA of load current. It features a linear temperature sensor output (TEMP) proportional to die temperature and includes a TRIM pin for fine voltage adjustment. The component is housed in an 8-pin SO package and functions within a -40°C to +125°C operating range.

Feature Summary

• Proprietary curvature-correction circuit and laser-trimmed thin-film resistors ensure low noise and high precision.
• Integrated TEMP pin provides a voltage output directly proportional to the internal die temperature.
• TRIM pin allows for fine adjustment of the preset output voltage 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 electronic systems
• Threshold detectors

Procurement Notes

Verify that the specific ordering suffix matches the required tolerance grade and packaging format. Confirm the device meets AEC-Q100 qualification requirements if intended for automotive applications. Ensure the input voltage differential remains sufficient for the selected load current to maintain regulation. Check for RoHS compliance status associated with the specific part number variant.

Selection Notes

Select this component when a stable +5.0V reference is required alongside integrated temperature sensing capabilities. The wide input voltage range accommodates varying supply rails up to 40V. Consider the quiescent current consumption for battery-powered designs. Verify that the thermal hysteresis characteristics align with the application's long-term stability requirements across the full temperature range.

Part Context

This device belongs to the MAX6173–MAX6177 family of high-precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares identical architectural features, including the proprietary curvature-correction circuit and short-circuit protection. Variations within the family are defined by their preset output voltages, ranging from +2.5V to +10V, while maintaining consistent performance metrics regarding noise, drift, and power consumption.

Replacement Considerations

Other members of the MAX6173–MAX6177 family may serve as functional replacements if the specific output voltage requirement differs. Verify that any substitute maintains the same 8-pin SO package dimensions and pinout configuration to ensure board compatibility.
