THS7353PWG4

TEXAS INSTRUMENTS  THS7353PWG4  缓冲放大器, 3 放大器, 35 MHz, 300 V/µs, 2.7V 至 5.5V, TSSOP, 20 引脚

DESCRIPON

Fabricated using the new complimentary silicon germanium SiGe BiCom-III process, the THS7353 is a low-power, single-supply 2.7-V to 5-V, 3-channel integrated video buffer. It incorporates a selectable 5th order Butterworth anti-aliasing / DAC reconstruction filter to eliminate data converter images. The 9-MHz is a perfect choice for SDTV video including composite, S-Video™, and 480i/576i Y"P"BP"R or G"B"R" R"G"B" video. The 16-MHz filter is ideal for EDTV 480p/576p Y"P"BP"R, G"B"R", and VGA signals. The 35-MHz filter is useful for HDTV 720p/1080i Y"P"BP"R, G"B"R", and SVGA/XGA signals. For 1080p or SXGA/UXGA signals, the filter can be bypassed allowing a 150-MHz bandwidth, 300-V/μs amplifier to buffer the signal.
