资 源 简 介
The OPA659 combines 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 front-end amplifiers and machine vision applicaTIons such as photodiode transimpedance amplifiers used in wafer inspection.
The wide 650MHz unity-gain bandwidth is complemented by a very high 2550V/µs slew rate.
The high input impedance and low bias current provided by the JFET input are supported by the low 8.9nV/ Hz input voltage noise to achieve a very low integrated noise in wideband photodiode transimpedance applications.
Broad transimpedance bandwidths are possible with the high 350MHz gain bandwidth product of this device.
