Product Summary

The OPA2228UA op amp combines low noise and wide bandwidth with high precision to make it the ideal choice for applications requiring both ac and precision dc performance. The OPA2228UA 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 op amp is ideal for professional audio equipment. In addition, low quiescent current and low cost make them ideal for portable applications requiring high precision. The OPA2228UA op amp is 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 perchannel cost reduction.
