•^{Operation notes}
(1) Operating power supply voltage range
Within the operating power supply voltage range, oper-
ation of the basic circuit functions is guaranteed for the
ambient operating temperature, but when using the
product, be sure that settings for constants and ele-
ments, voltage settings, and temperature settings are
carefully confirmed.
(2) Operating temperature
Within the recommended operating voltage range,
operation of the circuit functions is guaranteed for the
operating temperature range. Be aware that power dis-
sipation conditions are related to the temperature. Also,
except for conditions determined by electrical charac-
teristics within this range, the rated values for electrical
characteristics cannot be guaranteed, but the essential
functions are maintained.

(3) Application example
We guarantee the application circuit design, but recom-
mend that you thoroughly check its characteristics in
actual use. If you change any of the external compo-
nent values, check both the static and transient charac-
teristics of the circuit, and allow sufficient margin in
your selections to take into account variations in the
components and ICs.
Note that Rohm has not fully investigated patent rights
regarding this product.
