MAX6175BASA/V+

Overview

The MAX6175BASA/V+ is a high-precision voltage reference providing a fixed +5.0V output with ±0.06% initial accuracy and a maximum temperature coefficient of 3ppm/°C. It accepts input voltages from 7V to 40V, draws 320µA typical supply current, and sources up to 30mA or sinks 2mA. The device includes a linear temperature sensor output proportional to die temperature and features short-circuit protection. It operates over the -40°C to +125°C automotive range and is AEC-Q100 qualified.

Feature Summary

• Proprietary curvature-correction circuit and laser-trimmed thin-film resistors ensure low noise and high precision.
• Integrated linear temperature transducer provides an output voltage proportional to die temperature.
• TRIM pin allows fine adjustment of the output voltage using a resistive divider network.
• Stable without external output capacitors and supports capacitive loads up to 100µF.

Applications

• High-resolution analog-to-digital converters (ADCs)
• Digital-to-analog converters (DACs)
• Automotive electronic systems
• Precision digital voltmeters

Procurement Notes

Verify the specific suffix /V+ indicates AEC-Q100 qualification status as defined in the manufacturer's ordering information. Confirm the package code matches the required SOIC-8 footprint for your design. Ensure the input voltage range meets the minimum dropout requirements for the selected output load conditions.

Selection Notes

Select this component when a stable 5V reference with integrated temperature sensing is required. The wide input voltage range accommodates various supply rails. Verify that the 30mA sourcing capability meets the load requirements. Consider the TRIM functionality if tighter tolerance than the factory preset is necessary for the application.

Part Context

This part belongs to the MAX6173–MAX6177 family of high-precision voltage references. All members share identical architectures, including the temperature sensor and trim capabilities, differing only in their factory-preset output voltages (+2.5V, +3.3V, +4.096V, +5.0V, +10V). The MAX6175 specifically provides the 5.0V variant.

Replacement Considerations

Other members of the MAX6173–MAX6177 series are functionally compatible but provide different preset output voltages. Direct substitutes must match the 5.0V output requirement. Verify package compatibility and thermal characteristics when replacing with other manufacturers' devices.

FAQ

Does the MAX6175 require an output capacitor for stability?

No, the device does not require an output bypass capacitor for stability and remains stable with capacitive loads up to 100µF.

What is the function of the TEMP pin?

The TEMP pin provides a voltage output proportional to the die temperature, making the device suitable for temperature-sensing applications.

How can the output voltage be adjusted?

The output voltage can be finely trimmed by connecting a resistive divider network between the OUT, TRIM, and GND pins.
