说明

OPA690 器件代表了单增益稳定电压反馈运算放大器的一大进步。新的输入架构可提供压摆率和全功率带宽,以前只有宽带电流反馈运算放大器才具有这种特性。新的输出级架构可提供 215mA 的电流,且电流余量要求最小。这些功能相结合,可在 100Ω 负载条件下提供 1900V/µs 的出色压摆率。OPA690 具有 13ns 的超短稳定时间,因此非常适合快速采样系统,例如高速 ADC 驱动器、高速成像系统和电流 DAC 跨阻放大器。

OPA690 具有 6.1mA 的低静态电流,因此是便携式或电池供电型应用的理想选择。使用可选的禁用控制引脚 (DIS) 可以进一步降低系统功耗。DIS 保持断开或 DIS 保持高电平时将正常运行 OPA690。如果 DIS 被拉至低电平,OPA690 电源电流会降至 100µA 以下,同时输出进入高阻抗状态。
