SOP-8
S6419/PLow Power Audio Amplifier
Description
The S6419/P is a low power audio amplifier integrated circuit,
intended for the communication applications, such as in
speakerphones. It provides differential speaker outputs to
maximize output swing at low supply voltages.
Coupling capacitor to the speaker is not required. Open loop gain
is around 80dB, and the closed loop gain is set with two external
resistors [ Rf and Ri : refer to page 2].
A chips disable pin permits powering down and/or muting the
input signal.
Application
◈ Telephone
◈ Speakerphone

Description
This pin can be used to power down the IC to converse power, or for muting.
Enable(Open or less than 0.8V), Disable (2.0V to Vcc)
A capacitor at this pin increase PSRR and affects turn-on time. This pin can
be left open if the capacitor at pin 1 is sufficient.
