1.4W and 1W, Ultra-Small, Audio Power Amplifiers with Shutdown
General Description
The MAX4364/MAX4365 are bridged audio power amplifiers intended for portable audio devices with internal speakers.

The MAX4364 is capable of delivering 1.4W from a single 5V supply and 500mW from a single 3V supply into an 8 load. The MAX4365 is capable of delivering 1W from a single 5V supply and 450mW from a single 3V supply into an 8 load. The MAX4364/MAX4365 feature 0.04% THD+N at 1kHz, 68dB PSRR at 217Hz, and only 10nA of supply current in shutdown mode. The MAX4364/MAX4365 bridged outputs eliminate the need for output-coupling capacitors, minimizing external component count. The MAX4364/MAX4365 also include internal DC bias generation, clickless operation, short-circuit and thermal-overload protection. Both devices are unity-gain stable, with the gain set by two external resistors. The MAX4364 is available in a small 8-pin SO package. The MAX4365 is available in tiny 8-pin TDF
