Description External parts
Input coupling capacitor, which 1.0F recommended. potential input 2VBE (about 1.4V). Therefore, polarity must determined according potential circuit connected previous step LA42051. Capacitor ripple filter, which 100F recommended. Capacitor attenuation noise, which 4.7F recommended. Power supply capacitor. Output capacitor, which 470F recommended. Determine constant while taking into account fact that, with capacitance 470F less, roll-off frequency decreases range.

Standby function (pin amplifier turned ON/OFF through HIGH/LOW control amplifier turned when voltage 1.0V (min) more applied control voltage
Voltage Amplifier Standby
Insert limiting resistor (RSTB) when inrush current limited application voltage high. Example: when VS=5V, RSTB=5.1k inserted inrush current about 750A potential about 1.2V. Ripple filter MUTE function (Pin potential about VCC. Muting control output signal becomes effective shifting down with 500. Note that MUTE suppression rate decreases when resistance exceeds 750. Input (Pin potential input 2VBE (about 1.4V). Therefore, polarity must determined according potential circuit connected previous step LA42051. standard input resistance 30k. input capacitor, 1.0F recommended. starting time with power this case about 0.2s. starting time becomes about 1.5s when capacitance 10F. (Pin This attenuate noise during power OFF. Note that, with capacitance more, sound remain because signal off. (about 0.3V) -5.6V

Cautions
power fault (power supply output short-circuit) ground fault (GND output short-circuit) protective circuits incorporated, care must taken during use. thermal protective circuit incorporated, which activated when junction temperature (Tj) rises about 160°C more, controlling output gradually attenuated condition. During near maximum rating, product suffer damage slightest fluctuation condition exceeds maximum rating. sure product within range which never exceeds maximum rating while allowing sufficient margin supply voltage, etc.
