THS7315 具有 5 阶滤波器和 5.2V/V 增益的 3 通道 SDTV 视频放大器
Fabricated using the revolutionary complementary silicon-sermanium (SiGe) BiCom3 process, the THS7315 is a low-power, single-supply, 3-V to 5-V 3-channel integrated video buffer. It incorporates a 5th-order Butterworth filter that is useful as a digital-to-analog converter (DAC) reconstruction filter or an analog-to-digital converter (ADC) anti-aliasing filter. The 8.5-MHz filter is a perfect choice for SDTV video, including Composite Video Baseband Signals (CVBS), S-Video, Y’U’V’, G’B’R’ (R’G’B’), and Y’P’BP’R 480i/576i.
The THS7315 inputs can be either ac- or dc-coupled. The 230-mV output level shift allows for a full sync dynamic range at the output with 0 V input
