The MAX6241BCPA+ is a buried-zener series voltage reference providing a fixed 4.096V output in an 8-pin Plastic DIP package. It operates within a temperature range of 0°C to +70°C with a maximum temperature coefficient of 5ppm/°C and ±0.1% initial accuracy. The device supports input voltages from 8V to 36V, draws 3.2mA supply current, and handles source/sink currents up to 15mA.
Verify the specific suffix 'BCPA+' indicates the 0°C to +70°C operating range and 5ppm/°C temperature coefficient. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the procurement channel provides valid documentation matching the Analog Devices or Maxim Integrated datasheet specifications.
Select this component when a fixed 4.096V precision reference is required for commercial temperature ranges. The buried-zener architecture offers superior noise characteristics compared to bandgap references. Verify that the 15mA load regulation capability meets the system's sourcing and sinking requirements.
Part of the MAX6225/MAX6241/MAX6250 family of low-noise precision voltage references. The MAX6241 variant specifically provides a 4.096V output, distinguishing it from the 2.5V and 5V options within the same series. All devices share identical pinouts and feature sets.
Direct substitutes include other MAX6241 variants such as MAX6241ACPA+ (lower tempco) or MAX6241AEPA+ (extended temperature). Cross-family replacements require matching output voltage, package type, and noise specifications.
The output can be trimmed using a 10kΩ potentiometer connected between the OUT and GND pins, with the tap connected to the TRIM pin.
Add a 1μF capacitor to the NR pin to augment wideband noise reduction. Larger values do not significantly improve noise performance.
