Because a large current flows, it is
preferable to separate the GND line to
terminal GND (Pin13, Pin24) for the
speaker amplifier and other terminals
GND as much as possible on P board
pattern.
Output terminal of Rch speaker
amplifier. It is BTL output.
Rch positive aspect output pin:
Rch reverse-aspect output pin:
To decrease the voltage loss by the
wire resistance when maximum
outputting it, the output is made two
terminals. Please connect Pin14 to
Pin15 and Pin16 to Pin17 respectively
on P board pattern.
Terminal VCC to supply voltage to
speaker amplifier of Rch.
Terminal VCC to supply voltage to
speaker amplifier of Lch.
