Dual Wideband, Current-Feedback Operational Amplifier With Disable 数据表 
OPA2691为宽带双电流反馈运算放大器设定了新的性能水平。 OPA2691采用极低的5.1mA /ch电源电流工作，提供压摆率和输出功率，通常与更高的电源电流相关。新的输出级架构可提供高输出电流，并具有最小的电压余量和交叉失真。这提供了出色的单电源操作。采用+ 5V单电源供电，OPA2691可提供1V至4V输出摆幅，驱动电流超过150mA，带宽为190MHz。这些功能组合使OPA2691成为理想的RGB线路驱动器或单电源模数转换器（ADC）输入驱动器。
OPA2691的低5.1mA /ch电源电流经过精确调整在25°C。这种微调以及低温漂移确保了与竞争产品相比更低的最大电源电流。使用可选的禁用控制引脚（仅限SO-14）可以进一步降低系统功耗。将此禁用引脚保持打开状态或保持高电平可使其正常工作。如果拉低，OPA2691电源电流降至150μA/ch以下，同时输出进入高阻态。此功能可用于节省电力。
