OPA656NB

TEXAS INSTRUMENTS  OPA656NB  运算放大器, 单路, 500 MHz, 1个放大器, 290 V/µs, 10V 至 12V, ± 6V, SOT-23, 5 引脚

The 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.
