MAX6173BASA+T

Overview

The MAX6173BASA+T is a high-precision voltage reference providing a fixed +2.5V output with ±0.1% initial accuracy and a maximum temperature coefficient of 10ppm/°C over the -40°C to +125°C range. It accepts input voltages from (VOUT + 2V) up to +40V, draws 450μA maximum supply current, and sources 30mA or sinks 2mA. The device includes a linear temperature sensor output and a TRIM pin for fine adjustment.

Feature Summary

• Proprietary curvature-correction circuit ensures low temperature drift
• Integrated linear temperature transducer output proportional to die temperature
• TRIM input allows fine output voltage adjustment via resistive divider
• Stable without external output bypass capacitors

Applications

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

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and RoHS status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the ordering code matches the required electrical tolerance and temperature grade specifications.

Selection Notes

Select this part for applications requiring stable precision references with integrated temperature sensing capabilities. The wide input voltage range supports various supply rails. Verify that the 10ppm/°C temperature coefficient meets system accuracy requirements across the full operating temperature range.

Part Context
