数据： OPA695 Ultra-Wideband, Current-Feedback Operational Amplifier With Disable 数据表
OPA695是一款高带宽，电流反馈运算放大器，具有出色的4300-V /μs压摆率和低输入电压噪声，可提供精密，低成本，高动态范围的中频（IF）放大器。 OPA695针对高增益操作进行了优化，非常适合缓冲IF条带中的表面声波（SAW）滤波器，或者为电缆调制解调器上游线路驱动器提供低失真的高输出功率。在较低的增益下，可实现1400 MHz的更高带宽，使OPA695成为支持高分辨率RGB应用的出色视频线驱动器。
OPA695低12.9 mA电源电流精确调整为+25 C。这种微调以及低温漂移可在整个温度范围内提供较低的系统功率。使用可选的禁用控制引脚可以进一步降低系统功耗。将此引脚保持打开状态或保持高电平可以正常工作。如果拉低，OPA695电源电流将降至170μA以下。这种节能特性，以及出色的单+ 5V工作和超小型SOT23-6封装，使OPA695成为便携式应用的理想选择。
