Beschreibung von OPA656
The OPA656 combines a wideband, unity-gain stable, voltage-feedback operational amplifier with a low-noise 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.
The OPA656 features ultra-low input voltage noise (6nV/√Hz) to achieve a very low integrated noise in transimpedance applications. The combination of high input impedance and low input voltage noise makes the OPA656 an excellent wideband transimpedance amplifier in optical test and communication equipment, as well as medical and scientific instrumentation.
The OPA656 features a wide gain bandwidth of 230MHz. The large-signal bandwidth of 150MHz and low distortion make the OPA656 an excellent choice in high-speed digitizer front-ends, active probes, and other test and measurement front ends.
