Ideband, Unity Gain Stable FET-Input Operational Amplifier

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. 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/Hz input voltage noise to achieve a very low integrated noise in wideband Photodiode transimpedance applications. Broad transimpedance bandwidths are achievable given the OPA656s high 230MHz gain bandwidth product. As shown below, a 3dB bandwidth of 1MHz is provided even for a high 1M transimpedance gain from a 47pF source capacitance. By Texas Instruments
