Precision Dual Difet(R) Operational Amplifier - OPA2107

OPA2107 (ACTIVE)

Precision Dual Difet(R) Operational Amplifier

 

Special Note

See the OPA1688 for superior audio performance and lower power consumption.

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 parameters, such as input offset voltage, 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 DIP-8 and SO-8 packages.
