1.4W and 1W / Ultra-Small / Audio Power Amplifiers with Shutdown
General DescriptionThe 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 8Ωload. The MAX4365 is
capable of delivering 1W from a single 5V supply and
450mW from a single 3V supply into an 8Ωload. 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 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 thin QFN
(3mm ✕3mm ✕0.8mm) and µMAX packages.

ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

ELECTRICAL CHARACTERISTICS—3V
Note 2:All specifications are 100% tested at TA= +25°C.
Note 3:Quiescent power-supply current is specified and tested with no load on the outputs. Quiescent power-supply current
depends on the offset voltage when a practical load is connected to the amplifier.
Note 4:Common-mode bias voltage is the voltage on BIAS and is nominally VCC/2.
Note 5:Maximum differential-output offset voltage is tested in a unity-gain configuration. VOS= VOUT+- VOUT-.
Note 6:Output power is specified by a combination of a functional output-current test, and characterization analysis.
Note 7:Guaranteed by design, not production tested.
Note 8:Measurement bandwidth for THD+ N is 22Hz to 22kHz.
Note 9:Extended short-circuit conditions result in a pulsed output.
Typical Operating Characteristics(VCC= 5V, THD + N measurement bandwidth = 22Hz to 22kHz, TA= +25°C, unless otherwise noted.)
