MAX6175BASA+

Overview

The MAX6175BASA+ 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 load current. The device includes a TEMP pin for die temperature sensing and a TRIM pin for fine voltage 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 proportional to die temperature.
• Output voltage trimming capability via external resistive divider network.
• Short-circuit protection limits output current when shorted to ground or input.

Applications

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

Procurement Notes

Verify the specific suffix 'B' indicates the 0.1% accuracy grade if sourcing alternatives, as datasheet tables distinguish between 'A' (0.06%) and 'B' grades. Confirm the 'ASAP+' designation corresponds to the standard SOIC-8 package. Ensure the component meets RoHS compliance requirements for your assembly process.

Selection Notes

Select this part for applications requiring stable +5.0V references with minimal drift over wide temperature ranges. The integrated temperature sensor allows for on-die thermal monitoring without additional components. Consider the 7V minimum input requirement relative to your supply rails.
