SBOS196G – DECEMBER 2001 – REVISED NOVEMBER 2008  
Wideband, Unity-Gain Stable, FET-Input  
OPERATIONAL AMPLIFIER  
FEATURES  
DESCRIPTION  
● 500MHz UNITY-GAIN BANDWIDTH  
The OPA656 combines a very wideband, unity-gain stable,  
voltage-feedback op amp with a FET-input stage to offer an  
ultra high dynamic-range amplifier for ADC (Analog-to-Digital  
Converter) buffering and transimpedance applications. Extremely  
low DC errors give good precision in optical applications.  
● LOW INPUT BIAS CURRENT: 2pA  
● LOW OFFSET AND DRIFT: ±0.25mV, ±2µV/°C  
● LOW DISTORTION: 74dB SFDR at 5MHz  
● HIGH OUTPUT CURRENT: 70mA  
The high unity-gain stable bandwidth and JFET input allows  
exceptional performance in high-speed, low-noise integrators.  
● LOW INPUT VOLTAGE NOISE: 7nV/√Hz  
The high input impedance and low bias current provided by  
the FET input is supported by the ultra-low 7nV/√Hz input  
voltage noise to achieve a very low integrated noise in  
wideband photodiode transimpedance applications.  
APPLICATIONS  
● WIDEBAND PHOTODIODE AMPLIFIERS  
● SAMPLE-AND-HOLD BUFFERS  
● CCD OUTPUT BUFFERS  
Broad transimpedance bandwidths are achievable given the  
OPA656’s high 230MHz gain bandwidth product. As shown  
below, a –3dB bandwidth of 1MHz is provided even for a high  
1MΩ transimpedance gain from a 47pF source capacitance.  
● ADC INPUT BUFFERS  
● WIDEBAND PRECISION AMPLIFIERS
