330mW, Ultra-Small, Audio Power Amplifiers with Shutdown

All versions are No Longer Available. See Ordering Information for recommended replacements.

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 continuous 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 eliminate 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, programmable 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 TDFN and 8-bump UCSP™ chip-scale packages.
