General Description
The MAX4295 mono, switch-mode (Class D) audio
power amplifier operates from a single +2.7V to +5.5V
supply. The MAX4295 has >85% efficiency and is
capable of delivering 2W continuous power to a 4
load, making it ideal for portable multimedia and gener-
al-purpose high-power audio applications.
The MAX4295 features a total harmonic distortion plus
noise (THD+N) of 0.4% (fOSC = 125kHz), low quiescent
current of 2.8mA, high efficiency, and clickless power-
up and shutdown. The SHDN input disables the device
and limits supply current to <1.5A. Other features
include a 1A current limit, thermal protection, and
undervoltage lockout.
The MAX4295 reduces the number of required external
components. Internal high-speed power-MOS transis-
tors allow operation as a bridge-tied load (BTL) amplifi-
er. 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 or narrow SO package.
