OPA227U General Description

The OPA227U is an exceptional operational amplifier that offers a unique combination of low noise and wide bandwidth, making it ideal for applications that demand high precision in both AC and DC performance. With a high slew rate and wide bandwidth, the OPAx227 is unity-gain stable and perfect for professional audio equipment. Its counterpart, the OPAx228, is optimized for closed-loop gains of 5 or greater, providing even higher speed and performance with a slew rate of 10V/µs and a bandwidth of 33MHz. These operational amplifiers are designed for applications requiring high precision and low quiescent current, such as portable equipment. Additionally, the OPAx227 and OPAx228 series are pin-for-pin replacements for industry-standard OP27 and OP37, offering substantial improvements across the board. Available in DIP-8 and SO-8 packages, as well as DIP-14 and SO-14 packages for the OPA4227 and OPA4228, these amplifiers are suitable for various designs and configurations. With operation specified from -40°C to +85°C, the OPA227U is a versatile and reliable choice for precision applications
