Operation notes
The application example is recommended by ROHM, but before use in your application, be sure to carefully confirm
electrical characteristics.
Also, for use with different circuit constants for the external circuits, be sure to leave a sufficient margin for fluctuations in
characteristics in the external components and ROHM ICs in not only the static characteristics, but also the transient
characteristics as well.
