Description

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.
