3 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 650-MHz unity-gain bandwidth is complemented by a very high 2550-V/μs slew rate.
The high input impedance and low bias current provided by the JFET input are supported by the low 8.9-nV/√Hz input voltage noise to achieve a very low integrated noise in wideband photodiode transimpedance applications.
Broad transimpedance bandwidths are possible with the high 350-MHz gain bandwidth product of this device.
Where lower speed with lower quiescent current is required, consider the OPA656. Where unity-gain stability is not required, consider the OPA657.
