THS7313 使用 I2C 控制 +6dB 增益 SAG 修正 2:1 MUX 的 3 通道低功耗 SDTV 视频放大器

Fabricated using the new complimentary silicon-germanium (SiGe) BiCom-III process, the THS7313 is a low-power, single-supply 2.7-V to 5-V, 3-channel integrated video buffer. It incorporates a 5th order Butterworth filter which is useful as a digital-to-analog converter (DAC) reconstruction filter or an analog-to-digital converter (ADC) anti-aliasing filter. The 8-MHz filter is a perfect choice for SDTV video which includes composite (CVBS), S-Video, Y'U'V', G'B'R', and Y'P'BP'R 480i/576i.

Each channel of the THS7313 is individually I2C configurable for all functions which makes it flexible for any application. Its rail-to-rail output stage allows for both ac and dc coupling applications. The 6-dB gain along with the built-in SAG correction allows for maximum flexibility as an output video buffer
