Hi all,
Could you please tell me the optimal audio amp which meets the below requirements?

1. Output power: 1W / 8-ohm, Single-end output
2. Bi polar output (if possible)
2. Supply voltage: less than DC 8V
3. Analog input 
4. Ta: -20 to +70 deg C

Thanks in advance.
Regards,
Toshi

    Hi Toshi

    The TPA2001D1 meets the requirements. You could use the TPA2005D1 or TPA2006D1 too. But they have an output power a little bit higher than 1W. I recommend you to take a look these devices.

    Please let me know if you have more questions.

    Hi Figueroa-san,

    Thanks for your response.

    My customer's requirement is a single-end output because of their application.
    So that I think your recommended ICs do not meet the 1W output.

    If the power supply is grater than 8V, what is the recommendation?

    Thanks and regards,
    Toshi

    Hi Toshi-san

    Could you please tell me what you mean with Bipolar output?
    Unfortunately Low Power Audio Amplifiers can't be handled with voltages higher than 8V. They generally handle a maximum voltage from 5.5V.

    Please let me know your opinion.
