The recommended operating voltage range for the TDA1543A is 4.5V to 9V, with a typical voltage of 5V.
Proper thermal management for the TDA1543A can be achieved by providing a heat sink with a thermal resistance of less than 10°C/W, and ensuring good airflow around the device.
The maximum allowed input voltage for the TDA1543A is 2.5Vrms, exceeding which may cause distortion and affect the device's performance.
Optimizing the output filter design for the TDA1543A involves selecting the right values for the output capacitors and resistors to achieve a flat frequency response and minimize distortion. A good starting point is to use a 2nd-order Butterworth filter with a cutoff frequency of around 100kHz.
The recommended clock frequency for the TDA1543A is 256fs, where fs is the sampling frequency. For example, for a 44.1kHz sampling frequency, the recommended clock frequency would be 11.2896MHz.
