LA4814V no.a0972-5/17 cautions for use 1.input coupling capacitors (c1, c2) c1 and c2 are input coupling capacitors that are used to cut dc voltage. however, the input coupling capacitor c1 (c2) and input resistor r1 (r2) make up the high-pass filter, a ttenuating the bass frequency. th erefore, the capacitance value must be selected with due consid eration of the cut-off frequency. the cut-off frequency is expressed by the following formula : fc = 1/2 r1 c1 (= 1/2 r2 c2) note with care that this capacitance value affects the pop noise at startup. to increase this capacitance value, it is necessary to increase the capacitance value of pin 7 capacitor (c5) to soften the startup characteristics. 2.pin 7 capacitor (c5) this capacitor c5 is designed for the ripple filter. it s purpose is to make up a low-pass filter with a 100k internal resistor for reducing the ripple component of the power supply and improve the ripple rejection ratio. inside the ic, the startup characteristics of the pin 7 voltage are used to drive the automati c pop noise reduction circuit, and care must be taken with the pop noise when the c5 capacitance value is to be set lower. however, when the ic is used in btl mode, the automatic pop noise reduction function mentioned above has no effect. instead, a pop noise reduction method that utilizes the second amplifier control fu nction is used so that the capacitance value must be determined while factoring in the ripple rejection ratio or startup time. recommended capacitance value : min. 22 f (in 2-channel mode) 10 f (in mono btl mode) 3.bypass capacitor (c7) the purpose of the bypass capacitor c7 is to reject the high-frequency components that cannot be rejected by the power supply capacitor (chemical capacitor c6). place the capacitor as near to the ic as possible, and use a ceramic capacitor with excellent high-fre quency characteristics. 4.standby function the standby function serves to place the ic in standby mode to minimize the current drain. a) when using the standby function (when using microcomputer control) by applying the following voltages to the standby pin (pin 8), the mode changeover can be performed between standby and operation. operation mode v8 1.6v standby mode v8 0.3v however, set the resistance of resistor r5 inserted in series in such a way that the condition in the following formula is met. r5 24.6 (vstby - 1.6) k the pin 8 inrush current is expr essed by the following formula: i8 = (40 vstby - 26.3)/(1+0.04 r5) a fig. 1 b) when not using the standby function (microcomputer control is not possible) by applying a voltage from the power supply (pin 14) to the standby pin (pin 8), the ic can be turned on without the control of the microcomputer wh en the power is turned on. in order to reduce the pop noise when the ic is turned off, it is recommended that resistor r5 be inserted as shown in fig.2. the resistance value indicated below is recommended for the inserted resistor r5. v cc = 5.0v : r5 = 82k v cc = 3.6v : r5 = 47k v cc = 3.0v : r5 = 33k fig. 2 vstby stby r5 v8 8 r5 v cc v cc stby 14 8
LA4814V no.a0972-6/17 5.second amplifier control function (only when btl mode is used) the second amplifier control function is a function to reduce the startup pop-noise in btl mode. the pop noise can be reduced by first turning on the ic while the second amplifier is stopped, then after the potential inside the ic gets stabilized, turning on the second amplifier. the values shown below are r ecommended for the control time. c5 [ f] 2.2 3.3 4.7 10 twu [ms] 200 250 300 500 * twu : time after releasing standby to second amplifier turn-on a) when using microcomputer control the second amplifier can be controlled by applying the following voltages to pin 9. second amplifier operation mode v9 0.3v second amplifier stop mode v9 1.6v however, set the resistance value of the resistor r6 inserted in series in such a way that the condition in the following formula is met. r6 16.2 (vcnt - 1.6) k the pin 9 injected current is expressed by the following formula : i9 = (57.6 vcnt - 31.7)/(1+0.058 r6) a fig. 3 b) when microcomputer control is not possible when the microcomputer cannot be used, the second amplifier can be controlled by adding the external components as shown in fig. 4. v cc (v) 5 3.6 3 r7 (k ) 10 6.8 6.8 r9 (k ) 120 68 56 c8 ( f) 100 100 100 fig. 4 6.shorting between pins when power is applied with pins left short-circu ited, electrical deterioration or damage may result. therefore, check before power application if pins are short-circuited with solder, etc. during mounting of ic. 7.load shorting if the load is left short-circuited for a long period of time, electrical deterioration or damage may occur. never allow the load to short-circuit. 8.maximum rating when ic is used near the maximum rating, there is a po ssibility that the maximum rating may be exceeded even under the smallest change of conditions, resulting in failure. take su fficient margin for variation of supply voltage and use ic within a range where the maximum rating will never be exceeded. vcnt cn t r6 v9 9 + r8 100k r7 c8 r5 r9 v cc v cc cnt stby 14 9 8
LA4814V no.a0972-7/17 9.turn-off transient response characteristics if the ic is turned off and then turned back on while there is a potential difference between the pin 7 (reference voltage, plus input pin) and pins 5 and 10 (minus input pins), a louder pop noise than the one normally generated when power is switched on will be emitted. ther efore, in order to minimize the turn-on pop noise, smoothen the discharge of the input and output capacitors, and bring the potential of pin 7 and pins 5 and 10 to approximately the same level, then turn on the ic. a) single ended mode when the continuous changeover of mode between standby and operation is necessary, it is recommended to insert a resistor between the output pi ns (pins 3 and 12) and ground to accelerate the turn-off tran sient response characteristic. the value shown below is recommended for the resistor used for discharge. in order to reduce pop noise, it is recommended that time necessary for turning the ic back on is greater than the following value. recommended discharge resistor : r = 4.7k (recommended turn-on time : t = 600ms) b) btl mode when the continuous changeover of mode between standby and operation is performed, it is recommended that the second amplifier control function be used to reduce the turn-on pop noise. if this function is used, the pop noise level can be reduced regardless of the time taken for the ic to turn on after it is turned off. for details on the time taken for the second amplifier to turn on after the ic is turned on, refer to section 5 ?second amplifier control function.? pwr stby stby pwr 100ms/div out:50mv/div,ac 7pin:1v/div,dc t out1 in1 vre f 3 5 + - + c3 470 f r l 4 r3 33k r1 10k 10k c1 0.22 f 4.7k
