数据: LMH6629 Ultra-Low Noise, High-Speed Operational Amplifier with Shutdown 数据表
LMH6629是一款高速,超低噪声放大器,专为需要宽带宽,高增益和低噪声的应用而设计,如通信,测试和测量,光学和超声波系统。
LMH6629采用2.7 V至5.5 V电源供电,输入共模范围扩展至地下,输出摆幅仅为导轨的0.8 V以内用于单一供应应用。高频大信号可以驱动高达±250 mA的重负载,LMH6629的-3dB带宽为900 MHz,压摆率为1600 V /μs。 LMH6629(仅限WSON-8封装)具有用户可选的内部补偿,通过将COMP引脚拉低或拉高来控制4或10的最小增益,从而避免在竞争器件中需要外部补偿电容。 SOT-23-5封装的补偿在内部设置,最小稳定增益为10 V /V. WSON-8封装还提供掉电启用/禁用功能。
低输入噪声(0.69 nV /√ Hz 和2.6 pA /√ Hz ),低失真(HD2 /HD3 = -90 dBc /-94 dBc)和超低DC误差(800μVV< sub> OS 最大温度,±0.45μV/°C漂移)允许在交流和直流耦合应用中进行精确操作。
LMH6629采用德州仪器制造?采用专有的SiGe工艺,采用3 mm×3 mm 8引脚WSON封装和SOT-23-5封装。
