DESCRIPTION
The OPA2107 dual operational amplifier provides
precision Difet performance with the cost and space
savings of a dual op amp. It is useful in a wide range
of precision and low-noise analog circuitry and can be
used to upgrade the performance of designs currently
using BIFET® type amplifiers.
The OPA2107 is fabricated on a proprietary
dielectrically isolated (Difet ) process. This holds in-
put bias currents to very low levels without sacrificing
other important parameters, such as input offset volt-
age, drift and noise. Laser-trimmed input circuitry
yields excellent DC performance. Superior dynamic
performance is achieved, yet quiescent current is held
to under 2.5mA per amplifier. The OPA2107 is unity-
gain stable.
The OPA2107 is available in plastic DIP and SOIC
packages. Industrial temperature range versions are
available.
