MAX6176BASA+

Overview

The MAX6176BASA+ is a high-precision voltage reference providing a fixed +10V output. It features a maximum temperature coefficient of 3ppm/°C and an initial accuracy of ±0.1%. The device accepts input voltages from (VOUT + 2V) up to +40V, draws 550µA maximum supply current, and sources 30mA or sinks 2mA of load current. It includes a TEMP pin for die temperature sensing and a TRIM pin for fine voltage adjustment. The component operates over the -40°C to +125°C automotive temperature range in an 8-pin SO package.

Feature Summary

• Proprietary curvature-correction circuit with laser-trimmed thin-film resistors ensures low temperature drift and high precision.
• Integrated linear temperature transducer output proportional to die temperature for sensing applications.
• Output voltage trimming capability via external resistive divider network connected to the TRIM pin.
• Short-circuit protected output capable of sourcing 30mA without requiring external bypass capacitors for stability.

Applications

• High-resolution A/D and D/A converters
• Automotive systems
• Digital voltmeters
• Threshold detectors

Procurement Notes

Verify the specific suffix 'B' indicates the 0.1% accuracy grade rather than the tighter 0.05% grade found in other variants. Confirm the 'ASAP+' designation corresponds to the standard SOIC-8 package and RoHS compliance status as defined in the manufacturer's ordering information section.

Selection Notes

Select this part when a stable 10V reference is required alongside integrated temperature monitoring capabilities. Ensure the input voltage headroom meets the minimum dropout requirement relative to the 10V output. Consider the 30mA sourcing capability if driving moderate loads directly.

Part Context

This component belongs to the MAX6173–MAX6177 family of high-precision voltage references. While sharing identical architecture and feature sets, the MAX6176 variant is specifically factory-preset to deliver a +10V output level, distinguishing it from lower voltage options within the same series.

Replacement Considerations

Other members of the MAX6173–MAX6177 series share the same package and functional interface. Verify that alternative part numbers match the required output voltage and accuracy grade before substitution.

FAQ

Does the MAX6176BASA+ 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.

How is the output voltage adjusted on this component?

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