Pin descriptions • Pin 1 (power supply for R-ch. speaker power use) Please put a capacitor of about 100 µF between pin 1 and pin 5. • Pin 2, pin 3 (R-ch. speaker output) (BTL out) • Pin 4 (N.C.) • Pin 5 (GND for R-ch. speaker power use) • Pin 6, pin 45, pin 46, pin 47, pin 48, pin 49 (bass boost) Following equivalent circuit is for bass boost.

Pin descriptions (continued) • Pin 6, pin 45, pin 46, pin 47, pin 48, pin 49 (bass boost) (continued) 1) Pin 6 This pin makes first LPF together with internal registors. When a value of C2 is 0.1 µF, cutoff frequency is 160 Hz. 2) Pin 45, pin 46 This gain is VR6 + R9 GV = R9 It is necessary that VR6 = 10 kΩ, R9 = 10 kΩ for amplifier gain of two times. However this bass boost signal is mixed with the basis signal by speaker power amplifier on reverse phase, then if suitable value of VR6 is 75 kΩ. The HPF is composed with R9 and C27, then if R9 is 10 kΩ, suitable value of C27 is 1 µF. 3) Pin 47 This pin makes second LPF together with internal registors. When a value of C28 is 0.1 µF, peak gain frequency is 160 Hz. 4) Pin 48, pin 49 This purpose is DC cut. Suitable value of C29 is 4.7 µF (nonpolar), because input impeadance of speaker power amplifier is 2 kΩ. • Pin 7, pin 8 (L-ch., R-ch. speaker input) Suitable value of C3, C4 is 3.3 µF, because input impeadance of speaker power amplifier is 2 kΩ. Supposing that max output level of headphone is 1 V[rms], suitable value of R1, R2 is 25 kΩ, because gain of speaker power amplifier is 32 dB. • Pin 9 (ripple filter of speaker amplifier) Recommended value is 22 µF. If capacitor value is bigger, rise time at standby is longer. If capacitor value is smaller, rise time at stanby is shorter, but there are possibilities of pop sound occurrence and deterioration of power supply ripple rejection, cross talk and THD. • Pin 10 (power supply (speaker small signal use)) Please put a capacitor of 33 µF between GND (pin 38) and pin 10. • Pin 50 (bass boost limit control) Please put an about 10 kΩ register between pin 51 and GND. • Pin 51 (bass boost on/off switch) Suitable value of R11 is 50 kΩ and suitable value of C30 is 1 µF. Rise time is about 20 ms.
