Dear Sir,
We are estimating the playback time for a battery operating product.
When VDD = 3.6V, the total power consumption (excluding power use for sound producing) is typically 4mA for 8 ohm speakers.
If two speakers are drawing 2mA each to produce sound, the total power consumption of the LM4674A is typically 4+2+2 = 8mA. Am I correct? Is there other power consumption I need to consider?
