Description
The FAN7031 is a dual fully differential power amplifier in a
20-pin TSSOP-EP thermally enhanced package. When
delivering 1.85W of continuous RMS power into 4
speaker
at 5V supply, the FAN7031 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
FAN7031 provides shutdown function. Setting the shutdown
pin to ground level, the FAN7031 falls into shutdown mode
and consumes less than 4
μ
A over all supply voltage range,
2.7V to 5.5V. Two gain setting pins(G0 and G1) control the
gain 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 V
DD
/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 resistors
for gain setting and bootstrap capacitors are not needed,
making the FAN7031 well suited for portable sound systems
and other hand-held sound equipment. Target applications
include notebook and desktop computers and portable audio
equipment.
