OPA828 Overview
Description
The OPA828 and OPA2828 (OPAx828) JFET input operational amplifiers are the next generation OPA627 and OPA827, combining high speed with high dc precision and ac performance. These op amps supply low offset voltage, low drift over temperature, low bias current, and low noise with only 60-nVRMS 0.1-Hz to 10-Hz noise.
