The recommended PCB layout for the TDA9852H is to keep the analog and digital grounds separate, and to use a star-point grounding configuration to minimize noise and interference. Additionally, it is recommended to place the decoupling capacitors as close as possible to the IC pins.
To optimize the TDA9852H for low power consumption, it is recommended to use a low voltage power supply (e.g. 3.3V), to reduce the clock frequency, and to use the power-down mode when the device is not in use. Additionally, it is recommended to use a low-power oscillator and to minimize the number of active circuits.
The maximum allowed voltage on the analog input pins of the TDA9852H is 3.6V, which is the maximum rating for the device. However, it is recommended to keep the input voltage below 3.3V to ensure reliable operation and to prevent damage to the device.
To troubleshoot issues with the TDA9852H, it is recommended to check the power supply voltage, clock frequency, and input signals. Additionally, it is recommended to use an oscilloscope to monitor the output signals and to check for any signs of oscillation or instability. If the issue persists, it may be necessary to consult the datasheet or contact Philips Semiconductors support.
The TDA9852H is not compatible with 5V logic, as it is designed to operate at a maximum voltage of 3.6V. Using 5V logic with the TDA9852H may cause damage to the device or result in unreliable operation. It is recommended to use 3.3V logic or to use a level shifter to interface with 5V logic.
