OPA656 fet input wide bandwidth, lo noise opamp (4)
FET input, Wideband, Low Distortion, Low Noise OpAmp
The high unity-gain stable bandwidth and JFET input allows exceptional performance in high-speed, low-noise integrators.
The high input impedance and low bias current provided by the FET input is supported by the ultra-low 7nV/rtHz input voltage noise to achieve a very low integrated noise in wideband photodiode transimpedance applications.
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 1Mohm transimpedance gain from a 47pF source capacitance.
* 500MHz UNITY-GAIN BANDWIDTH
* LOW INPUT BIAS CURRENT: 2pA
* LOW OFFSET AND DRIFT: ±0.25mV, ±2µV/°C
