MAX6350CPA

Overview

The MAX6350CPA is a buried-zener series voltage reference providing a fixed +5V output. It features an initial accuracy of ±0.02% and a maximum temperature coefficient of 1.0ppm/°C. The device operates with an input voltage range of 8V to 36V and draws a typical supply current of 3.3mA. It supports sourcing and sinking currents up to 15mA, ensuring excellent load regulation. The component utilizes low-noise technology with a peak-to-peak noise of 3.0µV in the 0.1Hz to 10Hz band. It is housed in an 8-pin Plastic DIP package and functions within a commercial temperature range of 0°C to +70°C.

Procurement Notes

Verify that the specific part number matches the required package type and temperature rating. Confirm the ordering suffix corresponds to the desired operating range and physical form factor. Ensure compatibility with existing board layouts regarding the 8-pin Plastic DIP footprint. Cross-reference the manufacturer's latest documentation to confirm current production status and any potential design changes.

Selection Notes

Select this component when a stable +5V reference is required for high-resolution data conversion systems. Consider the buried-zener architecture for applications demanding minimal low-frequency noise. Evaluate the ±0.02% accuracy against system tolerance requirements. Verify that the 8V to 36V input range aligns with available power rails. Assess the need for external trimming if tighter voltage tolerances are necessary.

Part Context

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 voltages: 2.5V, 4.096V, and 5V respectively. All variants utilize the same low-power temperature-compensation scheme and offer optional noise reduction and voltage trim capabilities across various package options.

Replacement Considerations

Direct substitutes within the same family include MAX6325CPA (2.5V) and MAX6341CPA (4.096V), provided the output voltage requirement differs. Other packages such as MAX6350ESA or MAX6350EPA offer alternative thermal ratings or form factors while maintaining identical functionality.
