The MAX4364/MAX4365 are bridged audio power
amplifiers intended for portable audio devices with
internal speakers. The MAX4364 is capable of deliver-
ing 1.4W from a single 5V supply and 500mW from a
single 3V supply into an 8
capable of delivering 1W from a single 5V supply and
450mW from a single 3V supply into an 8
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 exter-
nal 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 TDFN (3mm
