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 > 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 >700MHz small-signal
bandwidth at a gain of 2, the OPA3875 gives a
typical 0.1dB gain flatness to > 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 <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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.
