Texas Instruments OPA659

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/s 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. view all in datasheet
