APPLICATIONS INFORMATION
cause the second form of clock feedthrough described
above, when averaged, dominate the DC input bias current
of the op amp below 70°C.
At temperatures above 70°C, the leakage of the ESD protec-
tion diodes on the inputs increases the input bias currents
of both inputs in the positive direction, while the current
caused by the charge injection stays relatively constant.
At elevated temperatures (above 70°C) the leakage current
begins to dominate and both the negative and positive
pins’ input bias currents are in the positive direction (into
the pins).
Extended Common Mode Range
The LTC2054/LTC2055 input stage is designed to allow
nearly rail-to-rail input common mode signals. In addition,
signals that extend beyond the allowed input common
mode range do not cause output phase inversion.
