Introduction

AI Translation

The OPAx22x series of operational amplifiers combines features such as low noise, wide bandwidth, and high precision. Therefore, they are ideal for applications that require both AC and precise DC performance. The OPAx227 has a stable unity gain, a high slew rate (2.3V/μs), and a wide bandwidth (8MHz). The OPAx228 is optimized for a closed-loop gain of 5 times or greater and offers higher speed, a 10V/μs slew rate, and a 33MHz bandwidth. The OPAx227 and OPAx228 series of operational amplifiers are well-suited for professional audio equipment. Additionally, their low quiescent current and low cost make them highly suitable for portable applications with strict requirements for high precision. The OPAx227 and OPAx228 series of operational amplifiers are pin-to-pin replacements for the industry-standard OP-27 and OP-37, with significant improvements across the entire circuit board. To save space and reduce the cost per channel, dual-channel and quad-channel versions are also available. The OPAx227 and OPAx228 come in DIP-8 and SO-8 packages. The OPA4227 and OPA4228 are packaged in DIP-14 and SO-14 with standard pin configurations. The rated operating temperature range is -40°C to 85°C.
