MAX442中文资料140MHz、2通道、视频多路复用放大器数据手册ADI规格书

描述 Description

The MAX442 combines a 140MHz video amplifier with a high-speed, 2-channel multiplexer in an 8-pin package. With its 36ns switching time and low differential gain (0.07%) and phase (0.09°) errors, it is ideal for broadcast-quality video applications. The device is designed to drive both 50Ω and 75Ω cables, and can directly drive a 75Ω load to ±3V.
The MAX442 video amplifier is compensated for unity-gain stability, and features a 140MHz bandwidth and a 250V/µs slew rate. The multiplexer's low input capacitance (4pF with the channel on or off) maximizes high-speed performance, and a ground pin separating the two input channels minimizes crosstalk and simplifies board layout.
The MAX442 operates from ±5V supplies and typically consumes 300mW. For applications that require more input channels, see the data sheets for the MAX440 8-channel mux/amp and the MAX441 4-channel mux/amp.
