The recommended PCB layout for the MAX4373FESA+T involves keeping the input and output traces as short as possible, using a solid ground plane, and placing the device close to the input capacitors. Additionally, it's recommended to use a Kelvin connection for the sense lines to minimize errors.
The MAX4373FESA+T does not require calibration for accurate voltage measurement. The device is factory-calibrated and provides a high degree of accuracy. However, if the user wants to achieve even higher accuracy, they can use an external calibration resistor to fine-tune the device.
The maximum voltage that can be applied to the input pins of the MAX4373FESA+T is 36V. Exceeding this voltage can damage the device. It's recommended to use input protection circuitry, such as a voltage limiter or a TVS diode, to prevent overvoltage conditions.
Yes, the MAX4373FESA+T can be used in high-temperature applications. The device is rated for operation from -40°C to +125°C. However, the accuracy and linearity of the device may degrade at higher temperatures. It's recommended to consult the datasheet and application notes for more information on high-temperature operation.
To ensure EMC when using the MAX4373FESA+T, it's recommended to follow proper PCB design and layout practices, such as using a solid ground plane, minimizing loop areas, and using shielding and filtering components. Additionally, the device should be placed in a shielded enclosure and connected to a low-impedance ground plane.
