LA42205 no.a0714-4/7 external components c1, c2 : input coupling capacitors. a value of 47 f is recommended. the input pin potential is 0.7v. c3 : capacitor which sets the starting time of the ripple filter and amplifier. a value of 100 f is recommended. c4, r1 : capacitor and resistor for muting function. c4 is necessary even when the mute function is not used. c5 : this capacitor increases the oscillator margin. we recommend a value of 0.1 f. c6 : power supply capacitor. 1. muting function (pin 7) the muting function is turned on when the pin 7 voltage is 1.5v (minimum) or higher. the v m applied voltage is set so that the pin 7 voltage will be 1.5v or higher. the muting time constant is determined by an c4, r1 circuit, and the component values must be determined by a careful analysis, since they are related to impulse noise that occurs when the muting function is turned on or off. also note that since c4 affects the occurrence of impulse noise when the amplifier is turned on or off, it will be required if the muting function is not used. 2. standby function (pin 6) the amplifier is turned on by applying a level of 2.5v (minimum) or higher to pin 6. pin 6 control voltage pin 6 voltage amplifier standby 0 to 0.5 off on 2.5 to v cc on off the limit resistor r stb may be inserted if the v stb applied voltage is comparatively high and there is a need to suppress the pin 6 sink current. mute standby + 7 c4 10 f /6.3v r1 15k 7.5k 1k v cc v m 20k 6 r stb 1.5k v cc 2v be v s 30k
LA42205 no.a0714-5/7 usage notes 1. this ic includes three short circuit protection circuits : shorting to power (shorts between an output and the power supply), shorting to ground (shorts between an output and ground), and load shorting protection circuits. these protection circuits operate wh ile the corresponding abnormal condition continues, and recover automatically when the abnormal condition is resolved. there are, however, cases wh ere, due to ic usage conditions, one of these protection circuits may lock and continue operating after the problem has been resolved. if this occu rs, the protection circuit stat e can be reset by either switching the ic to standby mode or by temporarily cutting power from the ic. 2. this ic includes a thermal protection circuit that operates if the junction temperature (tj) rises to 160c or higher. this circuit gradually reduces the output level. 3. if this ic is operated in the vicinity of any of its maximum ratings, even slight changes in operating conditions could result in a maximum rating being exceeded. since this could lead to the destruction of the ic, end product designs must include adequate margins in the supply voltage and other parameters so that the ic is always used within ranges such that the maximum ratings are never exceeded.
