Характеристики

OPA656U, Широкополосный операционный усилитель с единичным …The OPA656U is a very wideband unity-gain stable voltage-feedback Operational Amplifier with a FET-input stage to offer an ultra high dynamic-range amplifier for analog-to-digital converter (ADC) 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 OPA656 device’s high 230MHz gain bandwidth product.
