1.
“Recommend operating condition” is the conditions that the device functions properly, however
it dose not guarantee the limit of the particular performance.
2. “Electronic Characteristics” is DC and AC electronic specifications that guarantee the particular
performance limit. About the parameter, Specifications for which is not prescribed limit value
are not guaranteed,but typical value is the index of device performance. As for this, because
those parameters depend on circuit board layout design, parts and power supply design, those
are standard value under our company designation.
