Input coupling capacitor (C1 and C2) C1 (C2) is an input coupling capacitor that is used to cut the DC component. The input coupling capacitor C1 (C2) and the input resisters of 20kΩ (15kΩ + 5kΩ) make up a high-pass filter, attenuating the bass frequency. Therefore, the capacitance value must be selected with due consideration of the cut-off frequency. The cut-off frequencies are expressed by the following formulas. 1ch ⇒ fc1 = 1/ (2π × C1 × 20000) 2ch ⇒ fc2 = 1/ (2π × C2 × 20000) This capacitor affects the pop noise at startup. Note with care that increasing the capacitance value lengthens the charging time of the capacitor, which will make the pop noise louder. 2. Input coupling capacitors (C3 and C4) in the power amplifier block C3 (C4) is an input coupling capacitor that is used to cut the DC component. The input coupling capacitor C3 (C4) and the input resistor R1 (R3) make up a high-pass filter, attenuating the bass frequency. Therefore, the capacitance value must be selected with due consideration of the cut-off frequency. The cut-off frequencies are expressed by the following formulas. 1ch ⇒ fc3 = 1/ (2π × C3 × R1) 2ch ⇒ fc4 = 1/ (2π × C4 × R3) This capacitor affects the pop noise at startup. Note with care that increasing the capacitance value lengthens the charging time of the capacitor, which will make the pop noise louder. 3. BTL voltage gain of the power amplifier block The voltage gain of the first amplifier is determined by the ratio between the resistors R1 and R2 (R3 and R4). 1ch ⇒ Vg1 = 20 × log (R2/R1) … unit : dB 2ch ⇒ Vg2 = 20 × log (R4/R3) … unit : dB Therefore, the BTL voltage gain of the power amplifier block is expressed by the following formulas. 1ch ⇒ VgBTL1 = 6 + 20 × log (R2/R1) … unit : dB 2ch ⇒ VgBTL2 = 6 + 20 × log (R4/R3) … unit : dB The BTL voltage gain of the power amplifier block must be set in the range of 0 to 26dB. No.A1568-8/15 LV4985VH 4. pin 6 capacitor (C5) This capacitor is a ripple filter capacitor. The internal resistors (600kΩ + 50kΩ) and C5 make up a low-pass filter that is used to reduce the power supply ripple component and increase the ripple rejection ratio. Note that inside the IC, the rising-transient-response-characteristic of the pin 6 voltage (reference voltage) is used to activate the automatic pop noise reduction circuit. Therefore, when reducing the C5 capacitance value to increase the voltage rise speed, the design should take into account that the pop noise increases during voltage rise. 5. Power supply line capacitor (C6 and C7) The bypass capacitor C7 is used to remove the high frequency component that cannot be eliminated by the power supply capacitor C6 (chemical capacitor). Place the bypass capacitor C7 as near to the IC as possible, and use a ceramic capacitor with good high frequency characteristics. When using a stabilized power supply, these capacitors can also be combined into a single 2.2μF ceramic capacitor. Note that when the power supply line is relatively unstable, the power supply capacitor C6 capacitance value must be increased. 6. Load capacitance When connecting a capacitor between the output pin and ground to suppress electromagnetic radiation or other purposes, the effects of this capacitor may cause the power amplifier phase margin to be reduced, resulting in oscillation. When adding this capacitor, care should be taken for the capacitance value. Recommended capacitance value : 1000pF to 0.1μF 7. Headphone drive When also using the BTL amplifier’s first amplifier as the headphone amplifier, it is recommended to adjust the level by inserting series resistors R9 (R10) to the signal line as shown in Application Circuit Example-2. Note that this series resistor, the headphone load resistance and the output coupling capacitors C9 (C10) make up a high-pass filter, so this should be taken into account in the design. The cut-off frequencies are expressed by the following formulas. 1ch ⇒ fc5 = 1/ (2π × C9 × (R9 + RL)) 2ch ⇒ fc6 = 1/ (2π × C10 × (R10 + RL)) 8. Standby pin (pin 9) As shown in Figure1, by controlling the standby pin, the mode changeover can be made between standby mode, single-ended (SE) operating mode, and BTL operating mode. State Standby mode Pin 9 voltage Port A Port B 0V to 0.3V Low Low SE operating mode 1.3V to 1.7V High Low BTL operating mode 2.3V to VCC High High A-port B-port R5 R5 STBY 9 A-port R6 CPU LV4985VH Fig. 1 R5 9 STBY 9 STBY VCC 3 VCC CPU Fig. 2 Fig. 3 When not using the single-ended operating mode, a direct control is possible by connecting the standby pin to the CPU output port. However, it is recommended to insert a series resistor R5 (1kΩ or more) as shown in Figure 2 in case the pin is affected by the digital noise from CPU. In addition, when not using the standby mode, the pin 9 can also be used interlocked with the power supply as shown in Figure 3. Since there exists an internal current limiting resistor (30kΩ), the series resistor R5 can be eliminated, but the current I9 expressed by the following formula flows through the pin 9, so this should be taken into account in the design. Pin 9 inflow current (unit : A) : I9 = 4.7 × 10-6 + (VCC - 0.7)/(R5 + 30000) No.A1568-9/15 LV4985VH 9. Electronic volume control (pin 10 control) By changing voltage applied to the pin 10, the voltage gain of the built-in VCA(variable control amplifier) is varied. Since the ripple component of applied voltage is generated, a stabilized power source must be used. When controlling the amplifier using the PWM signal from the CPU, use a resistor and capacitor for DC conversion as shown in Figure 4 and adjust the voltage gain by changing the pulse width of PWM signal. In this case, the frequency of PWM signal used must be higher than audio frequency band. R7 PWM output 10 VOL C8 R8 CPU LV4985VH PWM signal Discharge resistor Fig. 4 10. Thermal protection circuit The IC has a built-in thermal protection circuit that can reduce the risk of breakdown or degradation when the IC becomes abnormally hot for some reason. When the internal chip junction temperature Tj rises to approximately 170°C, this protective circuit operates to cut off the power supply to the power amplifier block and stop signal output. Operation recovers automatically when the chip temperature drops to approximately 130°C. Note that this circuit cannot always prevent breakdown or degradation, so sufficient care should be taken for using the IC. When the chip becomes abnormally hot, immediately turn off the power and determine the cause. 11. Short-circuit between pins Turning on the power supply with the short-circuit between terminals leads to the deterioration and destruction of IC. When fixing the IC to the substrate, please check that the solder is not short-circuited between the terminals before turning on the power. 12. Load Short-circuit Leaving the IC in the load short-circuit for many hours leads to the deterioration and destruction of the IC. The load must not be short-circuited absolutely. 13. Maximum rating When the rated value used is just below to the absolute maximum ratings value, there is a possibility to exceed the maximum rating value with slight extrusion variable. Also, it can be a destructive accident. Please use within the absolute maximum ratings with sufficient variation margin of supply voltage. In addition, the package of this IC has low thermal radiation characteristics, so secure sufficient thermal radiation by providing a copper foil land on the printed circuit board near the heat sink.
