MAX6177BASA

Overview

The MAX6177BASA+ is a high-precision series voltage reference IC manufactured by Analog Devices under the Maxim Integrated brand. It provides a fixed output voltage of 3.3 V with an initial accuracy of 0.1% and a temperature coefficient of 3 ppm/°C. The device operates within an input voltage range up to 42 V and supports a maximum shunt current of 30 mA. It functions reliably across an extended temperature range from -40°C to +125°C. The component is housed in an 8-pin SOIC package, suitable for surface-mount assembly.

Feature Summary

• Delivers stable reference voltage with low temperature drift characteristics
• Supports wide input voltage range for flexible power supply integration
• Capable of sourcing significant load current for demanding applications

Applications

• Precision analog-to-digital converter (ADC) reference sources
• High-resolution digital-to-analog converter (DAC) excitation
• Calibration equipment requiring stable voltage standards
• Industrial sensor signal conditioning circuits

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm pinout and electrical specifications match design requirements. Confirm RoHS compliance status through manufacturer documentation. Check current availability constraints as distribution may be limited. Ensure the SOIC-8 package dimensions align with PCB footprint guidelines before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.3 V reference with 0.1% initial accuracy is required. Consider the 3 ppm/°C temperature coefficient for thermal stability needs. Evaluate the 30 mA output current capability against load demands. Verify compatibility with the operating temperature range of -40°C to +125°C for the intended environment.

Part Context

This part belongs to the MAX6177 series of precision voltage references designed for high-performance data acquisition systems. The series offers various output voltages and accuracy grades. The BASA variant specifically denotes the 3.3 V output version in an 8-pin SOIC package, targeting applications needing reliable voltage standards without complex external circuitry.

Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify that any substitute maintains identical output voltage, accuracy, and package dimensions. Ensure thermal performance and current capabilities meet or exceed original specifications.
