Product Summary

The OPA277PA is a high precision operational amplifier. The OPA277PA precision op amps replace the industry standard OP-177. The OPA277PA offers improved noise, wider output voltage swing, and are 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. Single, dual, and quad versions have identical specifications for maximum design flexibility. The OPA277PA op amp operates from ±2V to ±18V supplies with excellent performance. Unlike most op amps which are specified at only one supply voltage, the OPA277PA is specified for real-world applications; a single limit applies over the ±5V to ±15V supply range.
