Tool/software:

Hi team,

It's difficult to find headphone amplifiers on the updated homepage, so please recommend devices that meet the following criteria.

Analog input, 2 channels x 125mW / 32 ohms or higher, specifically designed for low power consumption

Best Regards,
Ryu.

    Hi Ryu,

    TPA6133A2 and TPA6130A2 (same but with I2C control) are they highest power headphone amplifiers.

    Hi Ivan,

    I am looking for the most power-efficient devices.
    Do these devices qualify as power-efficient?

    Best Regards,
    Ryu.

    Hi Ryu,

    Efficiency may be estimated from the power dissipation vs output power plot.
    These are competitive Class-AB amplifiers, and most importantly these are the highest power headphone amplifiers.

    If your application can use Class-D amplifiers, you can look at some of the TPA201xD2 and TPA202xD2 amplifiers, although these are usually driving lower impedance loads at higher power levels.
