OPA2277P

The OPA2277P is a high precision Operational Amplifier for use with precision integrators. It 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. Dual version has identical specifications, for maximum design flexibility. High performance is maintained as the amplifiers swing to their specified limits. Because the initial offset voltage (±20µV maximum) is so low, user adjustment is usually not required. OPA277 operational amplifier is easy to use and free from phase inversion and the overload problems found in some other operational amplifier. It is stable in unity gain and provides excellent dynamic behaviour over a wide range of load conditions. Dual version features completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded.
