OPA2228P Datasheet

Operational Amplifiers - Op Amps


The OPA227 and OPA2228P series op amps combine lownoise and wide bandwidth with high precision to make themthe ideal choice for applications requiring both ac and preci-sion dc performance.The OPA227 is unity-gain stable and features high slew rate(2.3V/µs) and wide bandwidth (8MHz). The OPA228 is opti-mized for closed-loop gains of 5 or greater, and offers higherspeed with a slew rate of 10V/µs and a bandwidth of 33MHz..The OPA227 and OPA2228P series op amps are ideal forprofessional audio equipment. In addition, low quiescentcurrent and low cost make them ideal for portable applica-tions requiring high precision.
