Product Summary
The OPA4228UA is a high precision, low noise operational amplifier. The OPA4228UA 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 OPA4228UA 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.
