Note 1) All voltage values are specified as VSS=0V.
Note 2) If the LSI is used on condition beyond the absolute maximum rating, the LSI may be destroyed.
Using LSI within electrical characteristics is strongly recommended for normal operation. Use beyond
the electrical characteristics conditions will cause malfunction and poor reliability.
Note 3) Decoupling capacitors should be connected between VDD-VSS due to the stabilized operation.

Note 4) When VDD Supply Voltage is lower than typical voltage, a pop noise may occur in output change
between BPZ and Audio Signal. Therefore, please consider and check the circuit carefully against pop
noise.
