high-speed
Two OPA4872s can be used together to form an
attenuator can be implemented by using an R-2R
8-input video multiplexer. The multiplexer is shown in
ladder together with the OPA4872. Figure 29 shows
such an implementation.
Channel 0 sees the full input signal amplitude, where
as channel 1 sees 1/2 VIN, channel 2 see 1/4 VIN and
channel 3 sees 1/8 VIN.

Three OPA4872s can be used together to form a
four-input RGB router. The router for the red
component is shown in Figure 30. Identical stages
would be used for the green and blue channels.

When
connecting
OPA4872
outputs
together,
maintain a gain of +1V/V at the load. The OPA4872
configuration shown is a gain of +6 dB; thus, the
matching resistance must be selected to achieve
–6 dB.
The set of equations to solve is shown in Equation 1
and Equation 2. Here, the impedance of interest is
75
.
