OPA4277PA vs OPA4277UA vs OP400EY Comparison

The OPA4277PA is a quad high precision Operational Amplifier offers improved noise, wider output voltage swing and is 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. Quad version has identical specifications, for maximum design flexibility. OPAx277 series operational amplifier operates from ±2 to ±18V supplies with excellent performance. Unlike most operational amplifier which is 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 amplifier swing to their specified limits. Because the initial offset voltage (±20µV maximum) is so low, user adjustment is usually not required. However, the single version (OPA277) provides external trim pins for special applications.
