OPA656 Description
The OPA656 bines a wideband, unity-gain stable, voltage-feedback operational amplifier with a lownoise junction gate field-effect transistor (JFET) input stage to offer an ultra high dynamic-range amplifier for transimpedance applications and high-speed data acquisition front-ends. Extremely low dc errors give good precision in both optical applications and test and measurement.
