The OPA27 and OPA37 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 OPA27 are unity-gain stable and features high slew rate (3.4V/µs) and wide bandwidth (8MHz). The OPA37 are optimized for closed-loop gains of 5 or greater, and offers higher speed with a slew rate of 11V/µs and a bandwidth of 33MHz.

The OPA27 and OPA37 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.

The OPA27 and OPA37 are available in DIP-8 and SO-8 packages.
