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 input bias currents to
very low levels without sacrificing other important param-
eters, such as input offset voltage, drift and noise. Laser-
trimmed input circuitry yields excellent dc performance. Su-
perior dynamic performance is achieved, yet quiescent cur-
rent is held to under 2.5mA per amplifier. The OPA2107 is
unity-gain stable.
The OPA2107 is available in DIP-8 and SO-8 packages.
