Product details

The MAX4411ETP+ is a Class AB stereo headphone amplifier from Maxim Integrated's DirectDrive® series, delivering 80 mW per channel into a 16 Ω load.

Built-in short-circuit and thermal protection mean the amplifier can survive a momentary output short or sustained high-drive without latching up or failing — a practical advantage in portable gear where headphone jacks get plugged and unplugged live. The Depop feature suppresses the audible pop on power-up and shutdown, which otherwise would require external muting circuitry.

The 20-TQFN (4x4 mm) with exposed pad is a compact, low-profile package. Surface-mount only.

Frequently asked questions

Does MAX4411ETP+ require external components?

The DirectDrive® architecture eliminates the need for large DC-blocking output capacitors. The part still requires supply bypass capacitors (typically 0.1 µF and 10 µF) and input coupling capacitors if the source has a DC offset. The datasheet application circuit shows the minimal external component count.

Can MAX4411ETP+ drive 32 ohm headphones?

Yes, the MAX4411ETP+ can drive 32 Ω headphones. Output power will be lower than into 16 Ω — approximately 40 mW per channel — which is still sufficient for typical listening levels with most consumer headphones.
