THS7374 具有 9.5MHz 滤波器和 6dB 增益的 4 通道 SDTV（组件和复合）视频放大器
Fabricated using the revolutionary complementary Silicon-Germanium (SiGe) BiCom3X process, the THS7374 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) which 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'), and Y'P'BP'R 480i/576i.
As part of the THS7374 flexibility, the input can be configured for either ac or dc-coupled inputs. The 300-mV output level shift allows for a full sync dynamic range at the output with 0-V input
