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

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.
