Product Summary
The OPA2227U/2K5 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 OPA2227U/2K5 is unity-gain stable and features high slew rate (2.3V/μs) and wide bandwidth (8MHz). The OPA2227U/2K5 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 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/2K5 is available in DIP-8 and SO-8 packages. The device is available in DIP-14 and SO-14 packages with standard pin configurations.
