When a value of C2 is 0.033 µF, cutoff frequency is 500 Hz. 2) Pin 45, pin 46 This gain is VR4 + R9 GV = R9 It is necessary that VR4 = 3.9 kΩ, R9 = 1 kΩ for amplifier gain of five times. The HPF is composed with R9 and C20, then if R9 is 1 kΩ, suitable value of C20 is 3.3 µF. 3) Pin 47 This pin makes second LPF together with internal registors. When a value of C21 is 0.033 µF, cutoff frequency is 500 Hz. 4) Pin 48, pin 49 This purpose is DC cut. Suitable value of C22 is 10 µF (bipolar), because input impeadance of speaker power amplifier is 2 kΩ. • Pin 7, pin 8 (L-ch., R-ch. speaker input) If no resistors are connected to pin 7 and pin 8 from previous stage, the BTL output has the gain of 40 times. If input of 1.4/40 V[rms] or more is possibly inputted, the input should be attenuated by connecting resistors to pin 7 and pin 8 from previous stage because the output dynamic range is about 1.4 V[rms]. The gain at BTL output is 2 kΩ/(R1+2 kΩ) × 40, where R1 and R2 are the resistance of resistors of connected to pin 7 and pin 8 from the previous stage and R1 = R2. Supposing that max output level of headphone is 1 V[rms], suitable value of R1 and R2 is 25 kΩ, because gain of speaker power amplifier is 32 dB. • Pin 9 (ripple filter of speaker amplifier) Recommended value is 1 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. 16 SDC00042BEB AN17000A ■ Applicaon Notes (continude) 1.

Suitable value of R3 is 25 kΩ and suitable value of C8 is 1 µF. • Pin 23 (N.C.) • Pin 24, Pin 25 (headphone amplifier L-ch., R-ch. input) Suitable value of C9, C10 is 1 µF, because input impedance of headphone power amplifier is 20 kΩ. If no resistors are connected to pin 24 and pin 25 from previous stage, the headphone amplifier has the gain of about 13 dB (at maximum volume). If input of 1.1/5 V[rms] or more is possibly inputted, the input should be attenuated by connecting resistors to pin 24 and pin 25 from previous stage because the output dynamic range is about 1.1 V[rms]. The gain is 20 kΩ/(R4+20 kΩ) × 4.5, where R4 and R5 are the resistance of resistors connected to pin 24 and pin 25 from the previous stage and R4 = R5. • Pin 26 (N.C.) • Pin 27, Pin 28 (line amplifier L-ch., R-ch. input) Suitable value of C11, C12 is 1 µF, because input impeadance of line amplifier is 50 kΩ. If no resistors are connected to pin 27 and pin 28 from previous stage, the line amplifier has the fixed gain of about 6 dB. If input of 1.1/2 V[rms] or more is possibly inputted, the input should be attenuated by connecting resistors to pin 27 and pin 28 from previous stage because the output dynamic range is about 1.1 V[rms]. The gain is 50 kΩ/(RX+50 kΩ) × 2, where RXs are the resistance of resistors connected to pin 27 and pin 28 from the previous stage. • Pin 29 (line amplifier R-ch. output) Suitable value of C13 is 1 µF. • Pin 30 (GND (line amplifier)) • Pin 31 (line amplifier L-ch. output) Suitable value of C14 is 1 µF. • Pin 32 (beep control (line amplifier)) A value of VR1 is bigger, output level is smaller. Around 10 kΩ is suitable as the maximum value for VR1. The beep output at line output is 0.9 × 10 kΩ/(1 kΩ+VR1) V[p-p], where VR1 is the resistance of the resistor between pin 34 and GND. • Pin 33 (line amplifier mute control) Suitable value of R6 is 75 kΩ and suitable value of C15 is 0.68 µF. 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. SDC00042BEB 17 AN17000A ■ Applicaon Notes (continude) 1.

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 36 (Speaker power selector) If this pin is left open, output power of 1 W or more is possible. If this pin is short-circuitted to GND, the output power is limited to 0.5 W. • Pin 37 (ripple filter (headphone)) A recommended value is 4.7 µF. If capacitor value is bigger, rise time at standby is longer. If capacitor value is smaller, rise time at standby is shorter, but there are possibilities of pop sound occurrence and deteriorations of power supply ripple rejection and cross talk and THD. • Pin 38 (GND (speaker small signal use)) • Pin 39 (volume control) Please put a variable volume of 50 kΩ or more between headphone VCC and headphone GND. • Pin 40 (ripple filter (line amplifier)) A recommended value is 4.7 µF. If capacitor value is bigger, rise time at standby is longer. If capacitor value is smaller, rise time at standby is shorter, but there are possibilities of pop sound occurrence and deteriorations of power supply ripple rejection and cross talk and THD. • Pin 41 (standby (line amplifire, headphone amplifier)) Swichting time depends on value of pin 37 and pin 40 capacitors. • Pin 42 (N.C.) Pin 42 connects to IC's heat sink. 1) Case of not using bass boost Please open pin 6, pin 47, pin 48, pin 49 and pin 50. Please connect pin 51 to GND. Please short between pin 45 and pin 46. 2) Case of not using line amplifire Please open pin 27, pin 28, pin 29, pin 31 and pin 32. Please connect pin 33 to GND. • Pin 43 (speaker mute control) Suitable value of R8 is 75 kΩ, suitable value of C19 is 0.68 µF. 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 44 (standby (speaker)) Swichting time depends on value of pin 9 capacitor. If value of C3 is 1 µF, rise time is about 80 ms. 18 SDC00042BEB AN17000A ■ Applicaon Notes (continude) 1.
