The input coupling capacitors C1, C2 and the input resistors R1 and R3 make up the 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/(2 x C1 x R1) 2ch fc2 = 1/(2 x C2 x R3) This capacitor affects the pop sound at startup. Note with care that increasing the capacitance value lengthens the charging time of the capacitor, which will make the pop sound louder. 2. BTL voltage gain The voltage gain of the first amplifier is determined by the ratio between the resistors R1 and R2 (R3 and R4). 1ch Vg1 = 20 x log(R2/R1) ...unit: dB 2ch Vg2 = 20 x log(R4/R3) ... unit: dB Therefore, the BTL voltage gain is expressed by the following formulas. 1ch VgBTL1 = 6 + 20 x log(R2/R1) ... unit: dB 2ch VgBTL2 = 6 + 20 x log(R4/R3) ... unit: dB The BTL voltage gain must be set in the range of 0 to 26 dB. 3. Beep signal input pin (pin 3) This pin is connected to the non-inverting input block of the first amplifier of the BTL amplifier, and is biased internally by a 50k resistor. The input coupling capacitor C4 and the bias resistor make up a high-pass filter that attenuates bass band signals, so when determining the C4 capacitance value, the value must be set with due consideration of the cut-off frequency. The cut-off frequency is expressed by the following formula. fc3 = 1/(2x C4 x 50000) In addition, when input from Pin 3, the BTL voltage gain is expressed by the following formulas. 1ch VgBTL1 = 6 + 20 x log(1+R2/(R1 + ro)) ... unit: dB 2ch VgBTL2 = 6 + 20 x log(1+R4/(R3 + ro)) ... unit: dB When setting the signal level, the signal should be attenuated and input as shown in Fig.1. When not using this input pin, connect it to pin 4 as shown in Application Circuit Example-2. LV49821VH other IC OUT ro 13 C1 R2 1 R1 C4 3 4 Beep signal in VREF C3 Fig.1 4. pin 4 capacitor (C3) This capacitor is a ripple filter capacitor. The internal resistors (100k + 450k) and C3 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 4 voltage (reference voltage) is used to activate the automatic pop sound reduction circuit. Therefore, when reducing the C3 capacitance value to increase the voltage rise speed, the design should take into account that the pop sound increases during voltage rise. 5. Power supply line capacitor (C7and C8) The bypass capacitor C8 is used to remove the high frequency component that cannot be eliminated by the power supply capacitor C7 (chemical capacitor). Place the bypass capacitor C8 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 2.2F ceramic capacitor. Note that when the power supply line is relatively unstable, the power supply capacitor C7 capacitance value must be increased. No.A1468-7/15 LV49821VH 6. Standby pin (pin 2) By controlling the standby pin, the mode changeover can be made between standby and operation modes. Direct control is possible using the CPU output port, but inserting a series resistor R5 (1 k or more) is recommended in case the pin is affected by digital noise from the CPU. Standby mode ... V2 = 0V to 0.3V 11 VCC Operating mode...V2 = 1.6V to VCC In addition, when not using standby mode, this pin can also be used interlocked VCC 2 STBY R5 with the power supply as shown in Fig. 2. The series resistor R5 can be eliminated, but the current I2 expressed by the following formula flows through the standby pin, so this should be taken into account in the design. Fig.2 Pin 2 inflow current (unit: A): I2 = 7 x 10-6 + (VCC - 0.7) / (R5 + 30000) 7. Pin 6 control (2nd amplifier stop control function) Pin 6 performs on/off control for the BTL amplifier's second amplifier operation. This function enables switching between speaker drive (BTL output system) and headphone drive (single end output system). The control comparator is connected to this pin, and this threshold voltage is generated by resistance division from the supply voltage. For this reason, care should be taken, as the threshold value varies according to the supply voltage. When switching using a headphone jack switch, the connection method shown in Application Circuit Example-1 is recommended. Comparator threshold value: Vth = VCC x 2/3 In addition, when controlling this pin with the CPU (BTL amplifier mute function), care should be taken for the relationship between the supply voltage used by the CPU and the supply voltage used by the power amplifier IC. When the supply voltage used by the power amplifier IC is higher, open/low format control as shown in Fig.3 and Fig.4 is recommended. In addition, there is also a control method that uses three resistors as shown in Fig.5. The recommended ratio between the resistance values of these three resistors is as follows. RC1, RC2, RC3 resistance ratio ... RC1 : RC2 : RC3 = 1 : 1 : 3 11 VDD VCC 6 A2CNT VCC CPU 11 VDD VCC 6 A2CNT I/O port CPU VCC I/O port I/O port CPU VCC RC1 RC2 11 VCC 6 A2CNT RC3 LV49821VH VSS Figure 3 LV49821VH VSS Figure 4 LV49821VH VSS Figure 5 8. 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 R6 and R8 to the signal line as shown in Application Circuit Example-1. Note that this series resistor, the headphone load resistance and the output coupling capacitors C5 and C6 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 fc1 = 1 / (2 x C5 x (R6 + RL)) 2ch fc2 = 1 / (2 x C6 x (R8 + RL)) 9. 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: 0.033F to 0.33F 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 130C. 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. No.A1468-8/15 LV49821VH 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. When VCC = 5V and load = 8, a ground line copper foil area of approximately 50mm x 50mm is recommended.
