Description
The FAN7033MP is a dual fully differential power amplifier
in a thermally enhanced 14-pin MLP package. When deliv-
ering 1.9W of continuous RMS power into 4Ω speaker at 5V
supply, the FAN7033MP has less than 1% of THD+N over
the entire audible frequency range, 20Hz to 20kHz. To save
power consumption in the portable applications, the
FAN7033MP provides shutdown function. Setting the shut-
down pin to ground level, the FAN7033MP falls into shut-
down mode and consumes less than 4µA over all supply
voltage range, 2.7V to 5.5V. Additional components such as
resistors for gain setting and bootstrap capacitors are not
needed, making the FAN7033MP well suited for portable
sound systems and other hand-held sound equipments. Tar-
get applications include the cellular phones, notebook, desk-
top computers, etc.
