!Operation notes
(1) Control pin (CTL)
The level of the DC voltage applied to the control pin should be in the range 0V to VCC. Appropriate switching may not be
possible in the region of the threshold voltage. Allow sufficient margin when setting this voltage.
(2) Recommended operating range
Provided the IC is operated within the operating temperature range and within the recommended operating conditions,
the general circuit functions are guaranteed to operate correctly, and there will not be significant changes in the electrical
characteristics.
(3) Application example
Provided the circuit constants in the application example circuit are used, the application circuit should function correctly.
However, we recommend that you confirm the characteristics of the circuit in actual use, and take note of the cautionary
items described above. If you change the circuit constants, check both the static and transient characteristics of the circuit,
and allow sufficient margin to accommodate variations in both the IC and the external components.
(4) License
The ICs are manufactured under license from BBB Sound Inc. (U.S.A.). A license agreement with BBB Sound Inc. is
required to use this component.
