Operational Amplifier, 1MHz, 0.8V/µs, SOIC-8

The OPA2277UA/2K5 is a high-precision operational amplifier designed to upgrade systems using the industry-standard OP-177, offering superior performance in critical areas. It provides improved noise characteristics, a wider output voltage swing, and operates at twice the speed with only half the quiescent current. This combination makes it an efficient and powerful choice for demanding analogue circuits.

Key features include an ultralow offset voltage and drift, minimal bias current, and exceptionally high common-mode and power supply rejection ratios. The series includes single, dual, and quad versions with identical specifications, granting maximum flexibility for your design without compromising on performance.

Unlike many operational amplifiers limited to a single supply rating, the OPAx277 series is specified for real-world conditions. It operates reliably from ±2V to ±18V supplies, with a single performance limit applied over the common ±5V to ±15V range, ensuring consistent operation as the output swings to its limits. The initial offset voltage is so low that user adjustment is typically unnecessary, though the single version does provide external trim pins for specialised applications.
