The ADG5408/ADG5409 are monolithic CMOS analog multiplexers comprising eight single channels and four differential channels, respectively. The ADG5408 switches one of eight inputs to a common output, as determined by the 3-bit binary address lines, A0, A1, and A2. The ADG5409 switches one of four differential inputs to a common differential output, as determined by the 2-bit binary address lines, A0 and A1. An EN input on both devices enables or disables the device. When EN is disabled, all channels switch off. The on-resistance profile is very flat over the full analog input range, which ensures good linearity and low distortion when switching audio signals. High switching speed also makes the parts suitable for video signal switching. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the power supplies. In the off condition, signal levels up to the supplies are blocked. The ADG5408/ADG5409 do not have VL pins; rather, the logic power supply is generated internally by an on-chip voltage generator.

产品详情

ADG5408/ADG5409均为单芯片CMOS模拟多路复用器，分别内置8个单通道和4个差分通道。ADG5408根据3位二进制地址线A0、A1和A2所确定的地址，将8路输入之一切换至公共输出。ADG5409根据2位二进制地址线A0和A1所确定的地址，将4路差分输入之一切换至公共差分输出。

两款器件均提供EN输入，用来使能或禁用器件。EN禁用时，所有通道均关断。导通电阻曲线在整个模拟输入范围都非常平坦，可确保开关音频信号时拥有良好的线性度和低失真性能。同时高开关速度使这些器件适合视频信号切换应用。

当接通时，各开关在两个方向的导电性能相同，输入信号范围可扩展至电源电压范围。在断开条件下，达到电源电压的信号电平被阻止。

ADG5408/ADG5409没有VL引脚；相反，逻辑电源由片内电压发生器在内部产生。
