High-Precision Operational Amplifier, OPA4277PA, Texas Instruments

The OPA277 precision operational amplifier replaces the industry standard OP-177. It offers improved noise performance, a wider output voltage swing, and is twice as fast with half the quiescent current. Features include ultra-low offset voltage and drift, low bias current, high common-mode rejection, and high power supply rejection. The OPA277 is easy to use and free from phase inversion and the overload problems found in some other op amps. It is unity-gain stable and provides excellent dynamic behavior over a wide range of load conditions. The OPA277 features fully independent internal circuitry that minimizes crosstalk and ensures freedom from interaction, even when overdriven or overloaded.

Features
