Applicaon Notes (continude)
1. Pin descriptions (continude)
Pin 45, pin 46, pin 47, pin 48, pin 49
Refer to pin 6.
Pin50 (bass boost AGC)
Connect this pin to GND with a resistor of 220 k
connected in parallel with a capacitor of 4.7
μ
F.
Pin 51 (bass boost on/off switch)
Suitable value of R11 is 75 k
and suitable value of C24 is 0.68
μ
F.
Rise time is about 20 ms.
If value of R and C is smaller, switching time is shorter but there is a possibility of pop sound occurrence.
Pin 52 (GND (L-ch. speaker power use))
Pin 53 (N.C.)
Pin 54, pin 55 (L-ch. speaker output) (BTL out)
Pin 56 (power supply (L-ch. speaker power use))
Please put an about 47
μ
F capacitor between pin 56 and pin 52.
