Output Bypass Switches
The IC’s includes two output bypass switches that solve
common applications problems. When a single trans-
ducer is used for the loudspeaker and receiver, the need
exists for two amplifiers to power the same transducer.
Bypass switches connect the IC’s receiver amplifier
output to the speaker amplifier’s output, allowing either
amplifier to power the same transducer. In systems where
an external receiver amplifier is used, route its output to
the left speaker through RECP/RXINP and RECN/RXINN,
bypassing the Class D amplifier. In systems where an
external amplifier drives both the receiver and the IC’s
line input, one of the differential signals can be discon-
nected from the receiver when not needed by passing it
through the analog switch that connects RECP/RXINP to
RECN/RXINN.
