* : Mounted on two-layer board of based on the JEDEC.
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) The relations of VDDO < VG must be maintained during operations.

Note 1) High side resistance and low side resistance depend on VG and VDDO. Therefore, VG and VDDO should be
adjusted on the application system.
Note 2) Output power using 8Ω speaker is 150mW(TYP:THD+N=10%) at the following condition.
→VDD=2.5V, VG=5.0V, VDDO1= VDDO2=3.0V
