Part Number: TAS2505
Other Parts Discussed in Thread: TPA301, , TPA2010D1, TPA2011D1, TPA2028D1

Hi

Our customer are considering the reference design as below. And they would like to replace the Audio amp which is TPA301 to TAS2505.

http://www.ti.com/tool/boostxl-audio?keyMatch=BOOSTXL-AUDIO&tisearch=Search-EN-Everything

Is that possible? If the device is not recommended,is there any recommendation?

(The requirement is "mono" and "4ohm 2W speaker" and "integrated volume control")

Best Regards,

Koji Hamamoto

    Hi K.Hamomoto-san,

    I think the TAS2505 is an overkill in this application.
    You could have a look at the following devices: TPA2011D1 and TPA2010D1. They are Class-D Audio Amplifiers and you could use the resistor network to set the volume. But I recommend you using a pre-amplifier to make the volume control, so you should place it before the Class-D Amplifier.
    Another option will be TPA2028D1 is a Class-D Audio Amplifier with Gain Control mediant I2C.
    Please let me know your thoughts.
