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.

產品詳情

ADG5408/ADG5409均為單芯片CMOS模擬多路復用器，分別內置8個單通道和4個差分通道。ADG5408根據3位二進制地址線A0、A1和A2所確定的地址，將8路輸入之一切換至公共輸出。ADG5409根據2位二進制地址線A0和A1所確定的地址，將4路差分輸入之一切換至公共差分輸出。

兩款器件均提供EN輸入，用來使能或禁用器件。EN禁用時，所有通道均關斷。導通電阻曲線在整個模擬輸入范圍都非常平坦，可確保開關音頻信號時擁有良好的線性度和低失真性能。同時高開關速度使這些器件適合視頻信號切換應用。

當接通時，各開關在兩個方向的導電性能相同，輸入信號范圍可擴展至電源電壓范圍。在斷開條件下，達到電源電壓的信號電平被阻止。

ADG5408/ADG5409沒有VL引腳；相反，邏輯電源由片內電壓發(fā)生器在內部產生。

產品聚焦

  溝槽隔離可防止閂鎖。電介質溝道將P溝道與N溝道晶體管分開，保證即使在嚴重過壓狀況下，也不會發(fā)生閂鎖現象。

  低導通電阻 RON。

  雙電源供電。對于雙極性模擬信號應用，ADG5408/ADG5409可以采用高達±22 V的雙電源供電。

  單電源供電。對于雙極性模擬信號應用，ADG5408/ADG5409可以采用最高40V的單軌電源供電。

  3 V邏輯兼容數字輸入：VINH = 2.0 V, VINL = 0.8 V.

  無需 VL 邏輯電源。
