OPA659 Overview
The OPA659 bines a very wideband, unity-gain stable, voltage-feedback operational amplifier with a JFET-input stage to offer an ultra-high dynamic range amplifier for high impedance buffering in data acquisition applications such as oscilloscope frontend amplifiers and machine vision applications such as photodiode transimpedance amplifiers used in wafer inspection. The wide 650-MHz unity-gain bandwidth is plemented...
