A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a 10uF capacitor between the AVDD and AGND pins to filter the analog supply.
Use the MAXIM's audio configuration tool or consult the application note AN5359 to determine the optimal configuration for your specific audio application. The tool helps you select the correct settings for the device's registers and pins.
The MAX9744ETH+T can handle up to 2.5W of power per channel. However, the actual power handling capability depends on the output impedance, supply voltage, and thermal considerations. Consult the datasheet and application notes for more information.
Check the power supply voltage, decoupling, and PCB layout. Ensure that the device is properly configured and that the input signals are within the specified range. Use an oscilloscope to analyze the output waveform and identify any distortion or noise sources.
Yes, the MAX9744ETH+T is suitable for battery-powered devices due to its low power consumption (typically 12mA) and low shutdown current (typically 1uA). However, ensure that the device is properly powered down when not in use to minimize power consumption.
