Product Summary
The OPA227PA is an op amp. It 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 OPA227PA is unity-gain stable and features high slew rate (2.3V/μs) and wide bandwidth (8MHz). The OPA227PA 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 OPA227PA is available in DIP-8 and SO-8 packages. The device is available in DIP-14 and SO-14 packages with standard pin configurations. The applications of the OPA227PA include data acquisition, telecom equipment, geophysical analysis, vibration analysis, spectral analysis, professional audio equipment, active filters and power supply control.
