TK15211
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 changed 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. The output
terminal voltage difference of the TK15211M is a value that adds the internal bias difference and the off-set voltage
difference. The value of the TK15211 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 circuit; even if V or GND is contacted, damage does not occur.
CC
The signal output terminal:
As for inflow, internal circuits are operated by constant current circuit; even if VCC 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 any terminal voltages over VCC +0.3 V or -0.3 V.
DC SIGNAL OUTPUT
The output of the TK15211M has a saturation voltage (both VCC and GND sides of approximately 1.0 V); accordingly the
use of a DC signal is not recommended (e.g., pulse signal etc.)
