The MAX4364/MAX4365 are bridged audio poweramplifiers intended for portable audio devices with internal speakers. The MAX4364 is capable of delivering1.4W from a single 5V supply and 500mW from a single 3V supply into an 8Ωload. The MAX4365 is capable of delivering 1W from a single 5V supply and 450mW from a single 3V supply into an 8Ω load. The MAX4364/MAX4365 feature 0.04% THD + N at 1kHz,68dB PSRR at 217Hz and only 10nA of supply currentin 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 twoexternal resistors.
The MAX4364 is available in a small 8-pin SO package.The MAX4365 is available in tiny 8-pin thin QFN(3mm× 3mm × 0.8mm) and µMAX packages.
