TK15324

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 TK15324M is a value that adds the internal bias difference and the off-set voltage difference. The

value of the TK15324M 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 VCC 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 VCC 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 +0.3 V or -0.3 V.

CC

DC SIGNAL INPUT

The output of the TK15324M has a saturation voltage (both VCC and GND 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.
