Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general best practices for audio circuit board design, such as separating analog and digital grounds, using a solid ground plane, and minimizing trace lengths and widths.
Proper biasing of the LM4836 involves setting the correct voltage on the VCC pin and ensuring that the input and output capacitors are properly sized and placed. Refer to the datasheet for specific recommendations on biasing and capacitor selection.
The maximum power dissipation of the LM4836 is dependent on the package type and ambient temperature. For the MTEX package, the maximum power dissipation is 1.4W. To ensure the device doesn't overheat, use a heat sink, ensure good airflow, and follow proper thermal design practices.
Yes, the LM4836 can be used in a stereo audio application. To configure it for stereo, use two separate LM4836 devices, one for each channel, and ensure that the input and output signals are properly routed and biased.
The recommended input impedance for the LM4836 is 10kΩ, and the recommended output impedance is 2kΩ. To match these impedances, use resistors and capacitors in the input and output stages, and ensure that the impedance is matched to the load and source impedances.
