The OPA227 and OPA228 series op amps combinelow noise and wide bandwidth with high precision tomake them the ideal choice for applicaTIons requiringboth ac and precision dc performance.The OPA227 is unity gain stable and features highslew rate (2.3V/ms) and wide bandwidth (8MHz). TheOPA228 is opTImized for closed-loop gains of 5 orgreater, and offers higher speed with a slew rate of10V/ms and a bandwidth of 33MHz.The OPA227 and OPA228 series op amps are idealfor professional audio equipment. In addiTIon, lowquiescent current and low cost make them ideal forportable applicaTIons requiring high precision.The OPA227 and OPA228 series op amps are pinfor-pin replacements for the industry standard OP-27and OP-37 with substantial improvements across theboard. The dual and quad versions are available forspace savings and per-channel cost reduction.The OPA227, OPA228, OPA2227, and OPA2228are available in DIP-8 and SO-8 packages. TheOPA4227 and OPA4228 are available in DIP-14and SO-14 packages with standard pin configurations.Operation is specified from –40°C to +85°C.
