APPLICATION INFORMATION (CONT.)
OUTPUT TERMINAL VOLTAGE DIFFERENCE
This parameter is the output voltage difference between Ach and Bch, and appears when the channel changes from Ach
to Bch, or changes to the reverse. Generally, this is called Switching Noise or Pop Noise. If this value is big and if this
noise is amplified by the final amplifier and is outputted by the speakers, then it appears as a Shock Sound. Output terminal
voltage difference of the TK15325M is a value that adds the internal bias difference and the off-set voltage difference. The
value of the TK15325M is very small; its maximum value is 3 mV. So almost the output bias difference will be decided by
the supply bias difference. Toko can offer the “Muting IC” if users wish to mute Switching Noise.
DIRECT TOUCH
The signal input terminals:
Internal circuits are operated by constant current circuit, even if V
CC
or GND is contacted, damage does not occur.
The signal output terminal:
Outflow or inflow current is decided by ability of final transistor, but protection circuit is not attached. If GND or V
CC
are
contacted damage may occur. Pay attention to long time contact. Do not supply over the maximum rating.
Referenced to GND, do not provide to all terminals over V
CC
+0.3 V or -0.3 V.
DC SIGNAL INPUT
The output of the TK15325M has a saturation voltage (both V
CC
and V
EE
sides about 1.0 V); accordingly the use of a DC
signal is not recommend (e.g., the pulse signal etc.)
NC TERMINAL
NC terminals are not wired inside IC by bonding wire. NC terminals are not tested so do not connect at outside.
