【

Note】6. The current flow direction of the input bias is out from the IC because the first stage of the IC composed of

PNP transistor. The current value is the value when the differential amplified circuit of the input stage is

balanced. When the comparator is active, twice the amount of current will flow to the pin with lower potential.

7. Current flowing through the internal circuit. This current flow regardless of the channel used.

8. Values when the input amplitude is 100 mV and the overdrive is 5 mV.Increasing the overdrive can shorten

the response time.
