说明

OPA695 是一款高带宽电流反馈运算放大器,具有出色的 5000V/μs 压摆率和低输入电压噪声,可提供精密、低失真、高动态范围放大器,以便在高速仪表系统中用作中间增益级。OPA695 针对高增益运行进行了优化,非常适合用于连接电流 DAC 输出,或用作高速数字转换器中的增益级,或用于为电缆调制解调器上行线路驱动器提供高输出功率和低失真。

OPA695 具有 14mA 的低电源电流(在 25°C 条件下)。使用可选的禁用控制引脚可以进一步降低系统功耗。该引脚保持开路或保持高电平可使器件正常运行。如果被拉至低电平,OPA695 电源电流将降至小于 160μA。这一省电特性连同出色的 5V 单电源供电特性和超小型 SOT23-6 封装,使得 OPA695 成为便携式应用的理想选择。

OPA695 具有 -40°C 至 +85°C 的宽额定工作温度范围。
