I'm looking for a class-D audio amplifier with speaker diagnostics.
I'm checking TDF8530TH/N2, TDF8597TH/N1, TDF8599CTH/N1.
1. We use 8 ohm speakers but the data sheet contains only the specifications for the 4 ohm and 2 ohm speakers.
I would like to know the following specifications for 8 ohm speakers.
- Recommended supply voltage.
- Max output.
- Output(W) to THD+N graph (according to audio frequency).
Specification of our device : THD+N is less than 3% when 1kHz audio, 20W output condition.
The output power difference between 200Hz(5kHz) and 1kHz should be within +-5dB.
2. Can I manually run DC diagnostics after the IC is powered on?
If possible, please let me know the sequence of S/W processing.
