Procurement Notes

Verify the specific suffix indicates RoHS compliance and lead-free status. Confirm the package type matches the required PCB footprint. Ensure the temperature grade aligns with the operational environment requirements. Check for any discontinuance notifications or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when high stability and low noise are critical for precision measurement applications. Consider the 5ppm/°C temperature coefficient for environments requiring strict thermal stability. Evaluate the need for external trimming if tighter tolerance than ±0.02% is required. Verify power supply constraints fit the 8V to 36V input range.

Part Context

This part belongs to the MAX6225/MAX6241/MAX6250 family of precision voltage references. The MAX6241 variant specifically targets the 4.096V output requirement. The 'BCSA' designation indicates a commercial temperature range and surface-mount SOIC packaging. The '+' suffix confirms lead-free manufacturing compliance.

Replacement Considerations

Direct replacements include other MAX6241 variants with different packages or temperature grades, such as MAX6241AEPA+ or MAX6241AMJA. Cross-family alternatives from Analog Devices should be evaluated based on pin compatibility and electrical specifications.

FAQ

How can the output noise be reduced?

A capacitor can be connected between the NR pin and ground to reduce wideband noise.

Is the output voltage adjustable?

Yes, the output can be trimmed by connecting a potentiometer between the OUT and GND pins, with the tap connected to the TRIM pin.
