Product Summary

The OPA2227U op amp combines low noise and wide bandwidth with high precision to make them the ideal choice for applications requiring both ac and precision dc performance. The OPA2227U is unity-gain stable and features high slew rate (2.3V/μs) and wide bandwidth (8MHz). The OPA228 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 OPA2227U op amp is ideal for professional audio equipment. In addition, low quiescent current and low cost make it ideal for portable applications requiring high precision. The OPA2227U 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. The OPA2227U is available in DIP-8 and SO-8 packages. The OPA2227U and OPA4228 are available in DIP-14 and SO-14 packages with standard pin configurations. Operation is specified from -40℃ to +85℃.
