The MAX6350ESA+ is a buried-zener series voltage reference providing a fixed 5V output. It features ±0.02% initial accuracy and a maximum temperature coefficient of 1ppm/°C. The device operates within an input voltage range of 8V to 36V and supports source/sink currents up to 15mA. Electrical characteristics include a typical supply current of 3.3mA, 3µVp-p noise (0.1Hz to 10Hz), and 30ppm/1000hr long-term stability. It is housed in an 8-pin SO package with an operating temperature range of -40°C to +85°C.
Verify the specific suffix 'ESA+' corresponds to the required 8-pin SOIC package and -40°C to +85°C temperature grade. Confirm that the ordering information matches the exact electrical specifications required for the application, particularly regarding the 1.5ppm/°C maximum temperature coefficient and ±0.02% initial accuracy limits defined for this variant.
Select this component when a fixed 5V precision reference is required for high-resolution data conversion systems. Ensure the design accommodates the specified 8V to 36V input voltage range and the 3.3mA typical supply current. Consider the optional TRIM and NR pins if circuit adjustments or further noise reduction are necessary for the specific application requirements.
This part belongs to the MAX6325/MAX6341/MAX6350 family of low-noise, precision voltage references manufactured by Analog Devices Inc./Maxim Integrated. The family utilizes buried-zener technology to achieve laboratory-standard temperature stability without requiring heated references. These devices are designed for applications demanding excellent line and load regulation.
