MAX6175BASA/V+T

Overview

The MAX6175BASA/V+T 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 (VOUT + 2V) up to +40V, draws 320μA typical supply current, and sources 30mA or sinks 2mA load current. The device includes a linear temperature sensor output proportional to die temperature and a TRIM pin for fine adjustment. It operates over the -40°C to +125°C automotive range in an 8-pin SO package.

Feature Summary

• Proprietary curvature-correction circuit and laser-trimmed thin-film resistors ensure low noise and high precision.
• Integrated linear temperature transducer output provides voltage proportional to die temperature.
• TRIM input allows fine adjustment of the output voltage using a resistive divider network.
• Short-circuit protected output capable of sourcing 30mA or sinking 2mA without external stability capacitors.

Applications

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

Procurement Notes

Verify the /V suffix indicates AEC-Q100 qualification status as specified in the ordering information section of the datasheet. Confirm the B grade corresponds to the 0.1% accuracy specification if required by design constraints. Ensure the tape-and-reel packaging matches the 'T' suffix designation for automated assembly processes.

Selection Notes

Select this component when a stable 5.0V reference is needed alongside integrated temperature sensing capabilities. The wide input voltage range supports applications with varying supply rails. Consider the 30mA source capability for driving moderate loads directly. Verify that the 8-pin SO package dimensions fit the available PCB real estate.

Part Context

This part belongs to the MAX6173–MAX6177 family of high-precision voltage references. The family shares identical architecture, featuring band-gap technology and proprietary curvature correction. Variations within the series provide different preset output voltages ranging from +2.5V to +10V while maintaining similar performance characteristics and package options.

Replacement Considerations

Other members of the MAX6173–MAX6177 series offer alternative fixed output voltages such as +2.5V, +3.3V, +4.096V, or +10V. These parts share the same pinout, package, and functional features, allowing for potential substitution if the specific voltage requirement differs.
