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,

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.
