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. STBY 4 10kΩ 30kΩ 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. about 50μA MUTE OFF ON MUTE 22 200Ω 10kΩ 18kΩ 1μF + about 2.5V Fig2 Mute equivalent circuit No.A1798-4/11 LV47004P 3. ACGND pin (pin 16) The capacitor of the pin 16 must use the same capacitance value as the input capacitor. Also, connect to the same PREGND as the input capacitor. 4. Self-diagnostics function (pin 25) By detecting the unusual state of the IC, the signal is output to the pin 25. Also, by controlling the standby switch after the signal of the pin 25 is detected by the microcomputer, the burnout of the speaker can be prevented. (1) Shorting to VCC/Shorting to ground : The pin 25 becomes the low level. (2) Load shorting : The pin 25 is alternated between the low level and the high level according to the output signal. (3) Output offset detection : when the output offset voltage exceeds the detection threshold voltage, the pin 25 becomes the low level. * Note: The output offset abnormality is thought of as the leakage current of the input capacitor. In addition, the pin 25 has become the NPN open collector output (active low). The pin 25 must be left open when this function is not used. 5V OFFSET DIAG 25 IN OUT+ + AC GND 16 + RT - - OUT- Output voltage Speaker pin output voltage +1.8V (typical) 0V -1.8V (typical) time 25 pin voltage time Fig3 Self-diagnosis Function Diagram No.A1798-5/11 LV47004P 5. Sound quality (low frequencies) By varying the value of input capacitor, low-frequency characteristic can be improved. However, it is concerned the shock noise. Please confirm in each set when the capacitance value varies. 6. Pop noise For pop noise prevention, it is recommended to use the muting function at the same time. • Please turn on the muting function simultaneously with power supply on when the amplifier is turned on. Next, turn off the muting function after the output DC potential stabilization. • When the amplifier is turn off, turn off the power supply after turning on the muting function. 7. Oscillation stability Pay due attention on the following points because parasitic oscillation may occur due to effects of the capacity load, board layout, etc. Board layout • Provide the VCC capacitor of 0.1μF in the position nearest to IC. • PREGND must be independently wired and connected to the GND point that is as stable as possible, such as the minus pin of the 2200μF VCC capacitor. In case of occurrence of parasitic oscillation, any one of following parts may be added as a countermeasure. Note that the optimum capacitance must be checked for each set in the mounted state. • Series connection of CR (0.1μF and 2.2Ω) between BTL outputs • Series connection of CR(0.1μF and 2.2Ω) between each output pin and GND.
