 Guide of model selection

Remarks:

1. The voice duration is based on 6K sample rate. Normally our sample rate is greater than 8K. Above duration is only for reference.
2. Each type chip could play chord.
3. Except for NV080C chip, while voltage is 5V and to connect “4007/4148”, chip’s voltage could be reduce under 4.5V .
