lv4991tt no.a0739-6/11 cautions for use 1. input coupling capacitor (c3) the input coupling capacitor c3 and input resistor r1 make up the high-pass filter, attenuating the bass frequency. therefore, the capacitance value must be selected with due consideration of the pass band. note with care that this capacitance value affects th e pop sound at startup. namely, the increased capacitance value will make the pop sound louder. 2. pin 3 capacitor (c4) this capacitor c4 is designed to reduce the power ripple. the ripple removal ratio increases when the capacitance is larger. note however that this capacitor affects the pop sound at startup. design must therefore be made by taking into both features as above described. 3. pin 4 control (second amplifier stop control function) pin 4 is a pin to turn on/off the operation of second amplif ier. by using this function, the pop sound at startup can be reduced. note that pin 4 can be controlled by applying the voltage described below : second amplifier on ? v4 = 1.6 to v cc v or open second amplifier off ? v4 = 0 to 0.3v when the pin-3 capacitor c4 is downsized, the pop sound becomes louder. the pop sound can be reduced by providing the time tmu to stop the second amplifier (see fig. 1) while utilizing this function of the microcomputor. the recommended mute time tmu is as follows. c4 [ f] 0.1 0.22 0.33 tmu [ms] 170 270 280 fig. 1 4. standby pin (pin 2) by controlling the standby pin, the mode changeover can be made between standby and operation modes. standby mode ? v2 = 0 to 0.3v operation mode ? v2 = 1.9 to v cc v when using the standby pin as interlocked with power supply as shown in fig. 2, care should be taken because the current i stby as expressed by the following equation flows through the standby pin. i stby = v cc ? 1.4v r3+21k ? fig. 2 v cc r3 v cc stby 7 2 pin 2:stby pin 4:cnt between pins 8 and 5: out1-out2 tmu time amp2:on
lv4991tt no.a0739-7/11 5. bypass capacitor (c2) of the power supply block the bypass capacitor attached to the power pin (pin 7) must be arranged as near to this pin as possible. 6. short-circuit between pins when power is applied with pins left short-ci rcuited, deterioration or damage may result. therefore, check before power application if pins are shor t-circuited with solder, etc. during mounting of ic to the substrate. 7. short-circuit of load if the load is left short-circuited for a long peri od of time, 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 possibility that the maximum rating may be exceeded even under the smallest change of conditions, resulting in failure. take the sufficient margin for variation of supply voltage and use ic within a range where the maximum rating will never be exceeded.
