FEATURES  
DESCRIPTION

•
HIGH BANDWIDTH: 650MHz (G = +1V/V)  
HIGH SLEW RATE: 2550V/µs (4V Step)  
EXCELLENT THD: –78dBc at 10MHz  
LOW INPUT VOLTAGE NOISE: 8.9nV/√Hz  
FAST OVERDRIVE RECOVERY: 8ns  
FAST SETTLING TIME (1% 4V Step): 8ns  
LOW INPUT OFFSET VOLTAGE: ±1mV  
LOW INPUT BIAS CURRENT: ±10pA  
HIGH OUTPUT CURRENT: 70mA  
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

Broad transimpedance bandwidths are possible with  
the high 350MHz 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.
