The FAN7031 is a dual fully differential power amplifier in a20-pin TSSOP-EP thermally  enhanced package. When  delivering 1.85W of continuous RMS power into 4? speakerat 5V supply, the FAN7031 has less than 1% of THD+N overthe entire audible frequency range, 20Hz to 20kHz. To savepower consumption in the  portable applications, the FAN7031 provides shutdown function. Setting the shutdownpin to ground level, the FAN7031 falls into shutdown modeand consumes less than 4A over all supply voltage range,2.7V to 5.5V. Two gain setting pins(G0 and G1)control thegain of the FAN7031. The gain is selectable to 6dB, 10dB,15.6dB and 21.6dB. The FAN7031 provides the single- ended(SE) operation by setting SE/BTL pin to above VDD/2.Using SE/BTL pin and a mechanical switch which provides at the headphone jack, SE mode and BTL mode are automat-ically determined. Additional components such as resistorsfor gain setting and bootstrap capacitors are not needed,making the FAN7031 well suited for portable sound systemsand other hand-held sound equipment. Target applicationsinclude notebook and desktop computers and portable audioequipment.
