APPLICATION INFORMATION
Operation Supply Voltage Range
The circuit functionality is guaranteed within operation of ambient temperature range, as long as it is within
operation supply voltage range. The standard electrical characteristic values are guaranteed at the test circuit
voltage of Vcc=5V. The cannot be guaranteed at other voltages in the operating range of 3.0V~16.0V, homever, the
variation will be small.

Power Dissipation
Refer to the thermal duration characteristics shown in Fig.3. Also, be sure to use this IC within a power dissipation
rage allowing enough margins.
Output and Bypass Capacitor
To prevent oscillations, place the output capacitor between the output pin and GND for both channel. There is a
possibility for oscillation if capacitor's value changes due to temperature, voltage, etc. More than 22μF electrolytic
capacitor is recommended. If an extremely large value of (over 1000μF) is used, it may cause oscillations at low
frequency. In case of using ceramic capacitor (it is recommended more than 10μF) connect with 1Ω resistance
