Caution: Operating supply voltage and operating temperature are the ranges in which the IC is available for basic operation.
(Basic operation means that the IC operates without emitting unexpected noise or stopping signal.)
Characteristics and rating are not warranted in the whole operating supply voltage and operating temperature.

(Note 2) The typical performance of device is shown Output Power and Voltage Gain. It largely depends on the board layout, parts, and power supply. The typical
values are measured with the device and parts mounting on surface of ROHM’s board directly and soldering thermal pad backside of package to top
layer cupper pattern of the board.
This IC is applicable to only dynamic speaker, not to other loads.
