THS7316DR

Fabricated using the Silicon- Germanium (SiGe) BiCom- III process, the THS7316 is a low power single- supply 3- V to 5- V, 3- channel integrated video buffer. It incorporates a 5th- order modified Butterworth filter which is useful as a DAC reconstruction filter or an ADC anti- aliasing filter. The 36- MHz filter is a perfect choice for HDTV video which includes Y'P'B'R 720p/1080i, G'B'R' (R'G'B'), and VGA/SVGA/XGA signals. As part of the THS7316 flexibility, the input can be configured for ac or dc coupled inputs. The DC + 140- mV input offset shift to allow for a full sync dynamic range at the output with 0- V input. The AC coupled modes include a transparent sync- tip clamp option for signals with sync such as Y' or Green with sync. AC- coupled biasing for P'B'R/Non- sync channels can be achieved by adding an external resistor. The THS7316 is the perfect choice for all output buffer applications. Its rail- to- rail output stage with 6- dB gain allows for both ac and dc line driving. The ability to drive 2 video lines per channel, or 75- Ω loads, allows for maximum flexibility as a video line driver. The 18.3- mA total quiescent current makes it an excellent choice for USB powered, portable, or other power sensitive video applications. The THS7316 is available in a small SOIC- 8 package that is RoHS compliant.
