OPA656 宽带单位增益稳定 FET 输入运算放大器

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 OPA656’s high 230MHz gain bandwidth product
