SBOS340 – DECEMBER 2006

Single 2:1 High-Speed Video Multiplexer

• 700MHz SMALL-SIGNAL BANDWIDTH

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

using a new input stage switching approach. This

technique uses current steering as the input switch

while maintaining an overall closed-loop design. With

• 0.025%/0.025° DIFFERENTIAL GAIN, PHASE

> 700MHz small-signal bandwidth at a gain of 2, the

OPA875 gives a typical 0.1dB gain flatness to

• HIGH GAIN ACCURACY: 2.0V/V ±0.4%

> 200MHz.

System power may be reduced using the chip enable

possible inputs.

Where three channels are required, consider using

the OPA3875 for the same level of performance.
