The OPA277U/2K5 is a high-precision operational amplifier designed for a variety of applications, including analog input modules, weigh scales, and data acquisition systems. It features an ultra-low offset voltage of 10 OºV and a low drift of ¬±0.1 OºV/¬8C, ensuring high accuracy in signal processing. The amplifier offers a high open-loop gain of 134 dB and excellent common-mode rejection of 140 dB, making it suitable for precision measurements. This device operates over a wide supply range of ¬±2 V to ¬±18 V and has a low quiescent current of 800 OºA per amplifier. It is available in multiple package types, including 8-SOIC, and is designed to be unity-gain stable, providing reliable performance across various load conditions. The OPA277U/2K5 is also noted for its low bias current of 1 nA maximum, which enhances its suitability for sensitive applications. Engineers may find this part particularly useful as it can replace older models such as the OP-07, OP-77, and OP-177, while offering improved performance characteristics. The device is rated for operation in temperatures ranging from -40¬8C to 85¬8C, making it versatile for both lab and field instrumentation.
