The OPA2277 precision operational amplifier replaces the industry standard OP-177. It offers improved noise, 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.
●OPA2277 operates from ±2-V to ±18-V supplies with excellent performance. Unlike most operational amplifiers, which are specified at only one supply voltage, the OPA2277 is specified for real-world applications; a single limit applies over the ±5-V to ±15-V supply range. High performance is maintained as the amplifiers swing to their specified limit. Because the initial offset voltage (±20 µV max) is so low, user adjustment is usually not required.
●OPA2277 is easy to use and free from phase inversion and overload problems found in some operational amplifiers. It is stable in unity gain and provides excellent dynamic behavior over a wide range of load conditions. OPA2277 features completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded. Dual versions are available in DIP-8, SO-8. OPA2277 is fully specified and operates from 55°C to 125°C.
