× 50 Watt power amplier and multiple voltage regulator
12.2 Beep input circuit
Beep input circuit to amplify the beep signal from the microcontroller to all 4 ampliers
(gain = 0 dB). Note that this circuit will not affect amplier performance.
12.3 Noise
The outputs of regulators 1 to 6 are designed to give very low noise with good stability.
The noise output voltage depends on output capacitor Co. Table 17 shows the affect of the
output capacitor on the noise gure.
