Description

General part information

OPA2228 Series

The OPAx227 and OPAx228 series operational amplifiers combine low noise and wide bandwidth with high precision to make them an excellent choice for applications requiring both ac and precision dc performance.

The OPAx227 are unity-gain stable and features high slew rate (2.3 V/µs) and wide bandwidth (8 MHz). The OPAx228 are optimized for closed-loop gains of 5 or greater, and offers higher speed with a slew rate of 10 V/µs and a bandwidth of 33 MHz.

The OPAx227 and OPAx228 series operational amplifiers are an excellent choice for professional audio equipment. In addition, low quiescent current and low cost make these op amps an excellent choice for portable applications requiring high precision.
