数据: LMH6654, LMH6655 Single and Dual Low Power, 250 MHz, Low Noise Amplifiers 数据表
LMH6654和LMH6655单高速和双高速电压反馈放大器设计为具有单位增益稳定工作,带宽为250 MHz。它们的工作电压范围为±2.5 V至±6 V,每个通道仅消耗4.5 mA电流。这些放大器具有极低的电压噪声和宽输出摆幅,可最大限度地提高信噪比,并具有真正的单电源供电能力,输入共模电压范围在负电压轨下方150 mV,在正电源轨的1.3 V范围内。 LMH6654和LMH6655的高速和低功耗组合使这些产品成为许多功耗非常高的便携式高速应用的理想选择。
LMH6654和LMH6655基于TI的Advance VIP10(垂直集成PNP)互补双极性工艺。
LMH6654采用5引脚SOT-23和8引脚SOIC封装。 LMH6655采用8引脚VSSOP(DGK)和8引脚SOIC封装。
