Hi Team,
We are using TAS2505TRGE-Q1 audio codec in our design.
As per my understanding, the SPL of the speaker and the gain of the class D amplifier are directly related. Presently we are supplying SPKVDD = 5 V and using a 2W rated speaker. However, since the gain is limited to 18 dB, the Output power of the codec is limited to 1.7/1.3 Watts approx.. Wanted to know the Max output power when the gain is increased to 24 dB as per section 7.3.6 of the datasheet for both THD=1% and THD=10%.
Also, If the Max Output power for a gain of 24 dB exceeds 2 Watt, kindly provide your thoughts regarding protection circuitry to be used for the same.
