2 APPLICATIONS System power may be reduced using the chip enable
feature for the OPA875. Taking the chip enable line
high powers down the OPA875 to less than 300ВµA
total supply current. Muxing multiple OPA875 outputs
together, then using the chip enable to select which
channels are active, increases the number of possible
inputs. RGB SWITCHING

DROP-IN UPGRADE TO LT1675-1 Where three channels are required, consider using
the OPA3875 for the same level of performance. EN

75W OPA875
(Patented) The OPA875 offers a very wideband, single-channel
2:1 multiplexer in an SO-8 or a small MSOP-8
package. Using only 11mA, the OPA875 provides a
gain of +2 video amplifier channel with greater
than 425MHz large-signal bandwidth (4VPP). Gain …
