The MAX6325CPA is a low-noise, precision voltage reference utilizing buried-zener technology. It provides a fixed 2.5V output with ±0.02% initial accuracy and an ultra-low temperature coefficient of 1ppm/°C maximum. The device operates within an input voltage range of 8V to 36V and supports source/sink currents up to 15mA. It features optional external trimming and noise reduction capabilities, ensuring stability for capacitive loads.
Verify the specific suffix 'CPA' indicates the Plastic DIP package and commercial temperature range (0°C to +70°C). Confirm that the ordering part number matches the required pin configuration and thermal specifications for your application environment before finalizing procurement.
Select this component when high precision and low noise are critical requirements. The buried-zener architecture offers superior stability compared to bandgap references. Ensure the input voltage remains between 8V and 36V and that the load current does not exceed 15mA sourcing or sinking limits.
This device belongs to the MAX6325/MAX6341/MAX6350 family of precision voltage references. While sharing identical electrical characteristics and pinouts, the family differentiates by fixed output voltage: 2.5V for MAX6325, 4.096V for MAX6341, and 5V for MAX6350.
