The OPA277P is a high precision Operational Amplifier offers improved noise, wider output voltage swing and are twice as fast with half the quiescent current. Features include ultralow 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 OPAx277 series operational amplifiers operate from ±2 to ±18-V supplies with excellent performance. Unlike most operational amplifiers which are specified at only one supply voltage, the OPAx277 series is specified for real-world applications; a single limit applies over the ±5 to ±15V supply range. High performance is maintained as the amplifiers swing to their specified limits, as the initial offset voltage (±20 µV maximum) is so low, user adjustment is usually not required. However, the single version (OPA277) provides external trim pins for special applications.
