Output terminal 
Using ±power supply, in case of the mode with DC offset, it is 
possible to use without capacitor of output by setting  
pin 5 to 0.6V-bias and by setting pins 7, 9, 11, 13, 15  to 
0.3V-bias. And in case of the mode without DC offset, it is 
possible to use without capacitor of output by setting each input 
to zero-bias. When using +power supply, both of the modes 
needs coupling capacitor.

Both ±power supply and +power supply are +VCC.

Specifications of any and all SANYO products described or contained herein stipulate the performance, 
characteristics, and functions of the described products in the independent state, and are not guarantees of 
the performance, characteristics, and functions of the described products as mounted in the customer's 
products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, 
the customer should always evaluate and test devices mounted in the customer's products or equipment.
SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all 
semiconductor products fail with some probability. It is possible that these probabilistic failures could give 
rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that 
could cause damage to other property. When designing equipment, adopt safety measures so that these 
kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits 
and error prevention circuits for safe design, redundant design, and structural design.
