125 mW per channel into 32 Ω
The MAX97220AETE+T is a Class AB stereo headphone amplifier from Analog Devices' DirectDrive series, delivering 125 mW per channel into a 32 Ω load. That output level is enough to drive consumer headphones to loud listening levels without an external coupling capacitor — the DirectDrive architecture generates a negative supply rail internally so the output sits at 0 V DC, eliminating the pop and thump of a DC-blocking cap.
