4 / 11 page LV47004P No.A1798-4/11 External Components Part Name Recommended Value Purpose Remarks C1 to C5 0.47 μF Cuts DC voltage The larger the constant value, the lower the cut-off frequency The values of C1 to C5 must be the same C6 22 μF Reduces ripples Reduces pop noise The larger the constant value, the longer the amplifier ON/OFF time C7 2200 μF Ripple filter Eliminating power supply ripples C8 0.1 μF Improves oscillation stability Reducing high-frequency noise C9 1 μF Reduces pop noise The larger the constant value, the longer the mute ON/OFF time R1 10k Ω Reduces pop noise The larger the constant value, the longer the mute ON/OFF time R2 4.7k Ω Pull-up resistor * The components and constant values within the test circuit are used for confirmation of characteristics and are not guarantees that incorrect or trouble will not occur in application equipment. Description of Operation 1. Standby switch function (pin 4) Threshold voltage of the pin 4 is set by about 2VBE. The amplifier is turned on by the applied voltage of 2.5V or more. Also, the amplifier is turned off by the applied voltage of 0.5V or less. Fig1 Standby equivalent circuit 2. Muting function (pin 22) The muted state is obtained by setting pin 22 to the ground potential, enabling audio muting. The muting function is turned on by the applied voltage of 1V or less to the resistance of 22pin (Mute pin). And the muting function is turn off tjis pin opens. Also, the time constant of the muting function is determined by external capacitor and resistor constants. It is concerned with a pop noise in amplifier ON/OFF and mute ON/OFF. After enough examination, please set it. Fig2 Mute equivalent circuit 4 STBY 10k Ω 30k Ω + MUTE MUTE OFF ON 10k Ω 18k Ω 1 μF about 50 μA about 2.5V 200 Ω 22 |
