LCD (1/3 duty , 1/2 bias)
Note: 1. T(transistor) = ß > 150, R2=470Ω ,S(speaker) = 1/4 w, 8
Ω;
all typical.
2. R2=470Ω ( typical ) to bypass extra current into base to get rid of waveform saturation on collector .
3. Piezo buzzer resonant frequency is around 1K Hz.
4. All the above components need to adjust possibly case by case to meet required performance.
5. Vout1,Vout2 are tristate during stand by.
