open-in-new Find other High-speed op amps (GBW>=50MHz)

Description

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 accuracy and switching glitch are improved over earlier solutions using a new input stage switching approach. This technique uses current steering as the input switch while maintaining an overall closed-loop design. With greater than 700MHz small-signal bandwidth at a gain of 2, the OPA875 gives a typical 0.1dB gain flatness to greater than 200MHz.

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 300µA 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.

Where three channels are required, consider using the OPA3875 for the same level of performance.
