LM4674A: Power Consumption

Part Number: LM4674A

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?

  • Hi, 

    Yes, typically the current consumption should be as you mentioned. Please remember that these typical current values were taken with the electrical characteristics conditions specified in the datasheet. Different conditions may result in different current values.

    Best regards,
