330mW, Ultra-Small, Audio Power Amplifiers

with Shutdown

General Description

The MAX4366/MAX4367/MAX4368 are bridged audio

power amplifiers intended for devices with internal

speakers and headsets. The MAX4366/MAX4367/

MAX4368 are capable of delivering 330mW of continu-

ous power into a 32Ω load, or 200mW into a 16Ω load

with 1% THD+N from a single 5V supply.

The MAX4366/MAX4367/MAX4368 bridged outputs elimi-

nate the need for output-coupling capacitors minimizing

external component count. The MAX4366/MAX4367/

MAX4368 also feature a low-power shutdown mode,

clickless power-up/power-down and internal DC bias

generation. The MAX4366 is a unity-gain stable, program-

mable gain amplifier. The MAX4367/MAX4368 feature

internally preset gains of 2V/V and 3V/V, respectively.

All devices are available in space-saving 8-pin SOT23,

thin QFN and µMAX packages, and an 8-bump chip-

scale package (UCSP™).
