The FAN7033MP is a dual fully differential power amplifier in a thermally enhanced 14-pin MLP package. When delivering 1.9W of continuous RMS power into 4 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 shutdown pin to ground level, the FAN7033MP falls into shutdown mode and consumes less than 4A 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. Target applications include the cellular phones, notebook, desktop computers, etc.
