Mono/stereo 2w Switch-mode (class-d) Audio Power Amplifiers Integrated ProductsThe MAX4295 MAX4297 mono/stereo, switch-mode
(Class-D) Audio Power Amplifiers operate from a single
+2.7V to +5.5V supply. They have >85% efficiency and
are capable of delivering 2W continuous power to a 4
load, making them ideal for portable Multimedia and
general-purpose high-power Audio applications.
The MAX4295 MAX4297 feature a total harmonic distor-
tion plus noise (THD+N) of 0.4% (fOSC = 125kHz), low
quiescent current of 2.8mA MAX4295 or 4.6mA
MAX4297 , high efficiency, and clickless power-up and
shutdown. The SHDN input disables the device and lim-
its supply current to <1.5A MAX4295 or <2.3A
MAX4297 . Other features include a 1A current limit,
thermal protection, and under-voltage lockout.
The MAX4295 (mono) and MAX4297 (stereo) reduce
the number of required external components. Both
devices have internal high-speed power-MOS transis-
tors, allowing operation as bridge-tied load (BTL) ampli-
fiers. The BTL configuration eliminates the need for
isolation capacitors on the output. The frequency-selec-
table pulse-width Modulator (PWM) allows the user to
optimize the size and cost of the output Filter
The MAX4295 is offered in a space-saving 16-pin
QSOP package, and the MAX4297 is offered in a com-
pact 24-pin SSOP package. By Maxim Integrated Products
