OPA3875中文资料具有 2:1 高速多路复用器的三通道、700MHz 运算放大器数据手册TI规格书

描述 Description

The OPA3875 offers a very wideband, 3-channel, 2:1 multiplexer in a small SSOP-16 package. Using only 11mA/ch, the OPA3875 provides three, gain of +2, video amplifier channels with greater than 400MHz large-signal bandwidth (4VPP). Gain accuracy and switching glitch are improved over earlier solutions using a new (patented) input stage switching approach. This technique uses current steering as the input switch while maintaining an overall closed-loop design. Gain matching between each of the 3-channel pairs is also significantly improved using this technique (<0.2% gain mismatch). With greater than 700MHz small-signal bandwidth at a gain of 2, the OPA3875 gives a typical 0.1dB gain flatness to greater than 150MHz. System power may be reduced using the chip enable feature for the OPA3875. Taking the chip enable line high powers down the OPA3875 to less than 900µA total supply current. Muxing multiple OPA3875 outputs together, then using the chip enable to select which channels are active, increases the number of possible inputs to the 3-channel outputs. Where a single channel of the OPA3875 is required, consider the OPA875.
