Application Information
1. REFERENCE INPUT
Pin 45 (REF) can use the reference Input pin .
• Reference input
2. SEPARATED CHANNEL MUTE FUNCTION
These pins are used for individual channel mute operation.
• When the mute pins (pin19, 20, 21 and 22) are high level, the mute circuits are activated so that the output circuit is muted.
• When the voltage of the mute pins (pin19, 20, 21 and 22) are low level, the mute circuit is stopped and output circuits
• If the chip temperature rises above 175 C, then the thermal shutdown (TSD) circuit is activated and the output circuits are
3. PROTECTION FUNCTION
• Thermal shutdown (TSD)
• Under voltage lockout (UVLO) and over voltage protection (OVP)
In the case of the reference input pin, you must keep the applied voltage range between 2[V] and 6.5[V] at V
operate normally.
muted.
- Mute 1 (pin 19)-CH1 mute control input pin.
- Mute 2 (pin 20)-CH2 mute control input pin.
- Mute 3 (pin 21)-CH3 mute control input pin.
- Mute 4 (pin 22)-CH4 mute control input pin.
If the chip temperature rises above 175 C, then the thermal shutdown (TSD) circuit is activated and the output circuit is will
be mute. The TSD circuit is temperature hysteresis 25 C.
It is designed to mute-operate the internal bias by the function of UVLO and OVP, when the power supply voltage falls
below 3.5[V] or above 20[V].
