Note 7: Timing specifications are guaranteed by design.

Note 8: Set by 1000pF external capacitor at the STO_ pin. t

is defined as the time from last input transition to STAT_ = high.

ASB

Does not include time to go into standby condition (t

ASBE)

Note 9:

is defined as the time from when STAT_ goes high to when the supply current drops to 5µA.

ASBE

Note 10: t

is defined as the time from the last input transition to when STAT_ goes low. The comparator is in high-speed mode

ASD

before STAT_ is low.

Note 11: t

is defined as the minimum input or LP pulse width to trigger fast-mode operation from auto-standby.

PWD

Note 12: t

Note 13: t

Note 14: t

is defined as the time from the last input transition to when the supply current increases to 300µA.

is defined as the time from when LP is driven high to when the supply current drops to 5µA.

is defined as the time from when LP goes low to when STAT goes low. The comparator is in high-speed mode before

STAT_ is low.

Note 15: t

Note 16: t

is defined as the time from when LP goes low to when the supply current increases to 300µA.
