Description
Terminal VCC to supply voltage to
speaker amplifier of L-channel.
Because of large current flows, it is
preferable to separate as much as
possible on the VCC system (Pin 18,
Pin 19 and Pin 47) on the PCB.
Output terminal of L-channel speaker
amplifier. It is BTL output.
L-channel positive aspect output pin:
Pin 22, Pin 23
L-channel reverse-aspect output pin:
Pin 20, Pin 21
To decrease the voltage loss across the
wire resistance during large current
flows, the output is made into two
terminals. Please connect Pin 20, Pin 21,
Pin 22, and Pin 23 respectively on the
PCB.
Terminal GND for speaker amplifier of
L-channel. It is not connected with the
substrate in IC.
Because of large current flows, it is
preferable to separate the terminal GND
(Pin 13 and Pin 24) for the speaker
amplifier and other terminals GND as
much as possible on the PCB.
