output pin, respectively, by the 8,7,6, added directly to the respective speakers. Amplifier gain Av -Rf/Ri, the maximum power consumption by the PDMAX 4VDD2/2RL. Input of external resistor and capacitor, respectively determine the input -3dB bandwidth taken Ci 1/(2 20k 20Hz), using about 0.39 F capacitor. LM4910 3 feet off the external control, when 3 feet to VDD (high level) when allowed to work, work prohibited ground (low level).
