TK15210
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 vice versa. 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 applied to the speakers, then it appears as a Shock Sound. The output terminal voltage
difference of the TK15210M is a value that adds the internal bias difference and the offset voltage difference. The value
of the TK15210 is very small; its maximum value is 18 mV. Toko can offer the “Muting IC” if users wish to mute Switching
Noise.
DIRECT CONTACT
The signal input terminals:
Internal circuits are operated by constant current circuits; even if V
CC
or GND is contacted, damage does not occur.
The signal output terminal:
As for inflow, internal circuits are operated by constant current circuits; even if V
is contacted, damage does not occur.
Outflow is protected by the circuit. Even if the terminal is contacted to GND, damage does not happen. Package damage
may occur due to heat. Pay attention to long time contact.
Do not supply over the maximum rating.
Referenced to GND, do not provide terminal voltages over V
CC
+0.3 V or -0.3 V.
DC SIGNAL OUTPUT
The output of the TK15210M has a saturation voltage (both V
and GND sides of approximately 1.0 V); accordingly the
use of a DC signal is not recommended (e.g., pulse signal, etc.).
