THS7375IPWR

4通道SDTV视频放大器， 6阶滤波器和5.6 -V / V增益 4-Channel SDTV Video Amplifier with 6th-Order Filters and 5.6-V/V Gain

Fabricated using the revolutionary complementary Silicon-Germanium SiGe BiCom3X process, the THS7375 is a low-power, single-supply, 3 V to 5 V four-channel integrated video buffer. It incorporates a sixth-order Butterworth filter able to be bypassed that is useful as a digital-to-analog converter DAC reconstruction filter or an analog-to-digital converter ADC anti-aliasing filter. The 9.5-MHz filter is a perfect choice for SDTV video that includes composite CVBS, S-video, Y"U"V", G"B"R" R"G"B", Y"P"BP"R 480i/576i, and SCART systems.

As part of the THS7375 flexibility, the input can be configured for either ac or dc-coupled inputs. The 320-mV output level shift allows 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 CVBS, Y", and G"B"R" signals with sync. AC-coupled biasing for C"/P"B/P"R channels can easily be achieved by adding an external resistor to VS+.

The THS7375 is the perfect choice for all video buffer applications. Its rail-to-rail output stage with 5.6-V/V gain allows for both ac and dc line driving. This architecture makes the THS7375 an ideal choice for DaVinci™ processors. The ability to drive two lines per channel, or 75-Ω loads, allows for maximum flexibility as a video line driver. The 9.8-mA total quiescent current at 3.3 V and 0.1-µA disabled current makes it an excellent choice for USB-powered, portable, or other power-sensitive applications.

The THS7375 is available in a TSSOP-14 package that is lead-free and green RoHS compliant.
