Be sure to use SVCC in the maximum potential. Otherwise, it is likely to cause an operating error. 2. On driver gain setting, Power amp. voltage gain: 23 dB 3. On operating mode of mute, 1) Driver PC1 PC2 High Low (open) High Low (open) Channel 1 Active Mute ¾¾ Channel 2 ¾¾ Active Mute 2) General-use op-amp. PC1 High Low (open) PC2 High Active Active Low (open) Active Mute 4. Appropriate care should be taken on the characteristics. When changing an external circuit constant on actual use, secure an appropriate margin in consideration of charac- teristic fluctuation of external parts and our ICs including transient characteristics as well as static ones. 5. Avoid the short-circuits between output pin and V CC , output pin and GND (line-to-supply and line-to-ground), and between output pins (load short-circuit). Otherwise, the IC is likely to emit smoke and break down. 6. An appropriate prior study should be done for use of dip soldering.
