Introduction

AI Translation

The OPAx22x series operational amplifiers combine low noise and wide bandwidth with high precision to make them the ideal choice for applications requiring both AC and precision DC performance. The OPAx227 is unity-gain stable and features high slew rate (2.3V/μs) and wide bandwidth (8MHz). The OPAx228 is optimized for closed-loop gains of 5 or greater, and offers higher speed with a slew rate of 10V/μs and a bandwidth of 33MHz. The OPAx227 and OPAx228 series operational amplifiers are ideal for professional audio equipment. In addition, low quiescent current and low cost make them ideal for portable applications requiring high precision. The OPAx227 and OPAx228 series operational amplifiers are pin-for-pin replacements for the industry standard OP-27 and OP-37 with substantial improvements across the board. The dual and quad versions are available for space savings and per channel cost reduction. The OPAx227, OPAx228, are available in DIP-8 and SO-8 packages. The OPA4227 and OPA4228 are available in DIP-14 and SO-14 packages with standard pin configurations. Operation is specified from -40°C to 85°C.
