The recommended PCB layout for the MAX9728AEUD+ is to keep the analog and digital grounds separate, use a solid ground plane, and keep the input and output traces as short as possible. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To optimize the performance of the MAX9728AEUD+ in a noisy environment, use a ferrite bead or a common-mode choke on the input lines, add a 10nF to 100nF capacitor between the input lines and ground, and use a shielded cable or a twisted pair for the input signals.
The maximum power dissipation of the MAX9728AEUD+ is 1.4W, which is calculated based on the maximum operating junction temperature of 150°C and the thermal resistance of the package.
Yes, the MAX9728AEUD+ is AEC-Q100 qualified, which means it meets the requirements for automotive applications. However, it's recommended to check the specific requirements of the application and ensure that the device meets those requirements.
To troubleshoot issues with the MAX9728AEUD+, start by checking the power supply voltage, ensuring that it's within the recommended range. Then, check the input signals, ensuring that they're within the recommended range and not clipping. Finally, check the output signals, ensuring that they're not distorted or clipped.
