Overview
The OPA2107AU/2K5 is a precision dual operational amplifier manufactured by Texas Instruments. It offers high performance with the cost and space savings of a dual op amp, making it suitable for a wide range of precision and low-noise analog circuitry. The OPA2107 is fabricated on a proprietary dielectrically isolated (Difet) process, which maintains very low input bias currents without compromising other critical parameters such as input offset voltage, drift, and noise. Laser-trimmed input circuitry ensures excellent DC performance, and the amplifier achieves superior dynamic performance while keeping the quiescent current under 2.5mA per amplifier. The OPA2107 is unity-gain stable and available in DIP-8 and SO-8 packages.
