†
All characteristics are measured under open-loop conditions, with zero common-mode input voltage, unless otherwise specified.
‡
Full range is −40°C to 125°C.
§
All typical values are at T
A
= 25°C.
¶
Due to proximity of external components, ensure that coupling is not originating via stray capacitance between these external parts. Typically,
this can be detected, as this type of coupling increases at higher frequencies.
