OPA860 APPLICATIONS
The OPA860 is comprised of both the OTA section
and the Buffer section. This applications information
focuses more on using both sections together to form
various useful amplifiers. A more thorough description
of the OTA section in filter applications can be found
in the
OPA861
datasheet, available for download at

E-follower—a voltage buffer. It is interesting to notice
that the larger the R
E
resistor, the closer to unity gain
the buffer will be. If the OTA section is to be used as
a buffer, use R
E
≥
500
for best results. For the OTA
section used as a buffer, the gain is given by
