描述

Fabricated using the revolutionary, complementary Silicon-Germanium (SiGe) BiCom3X process, the THS7319 is a very low-power, 2.6-V to 5-V single-supply, three-channel, integrated filter video buffer. This device is ideal for battery-powered applications where size and power are critical parameters. Total quiescent current is only 3.4 mA at 3.3 V and can be reduced to 0.15 µA while disabled.

The THS7319 incorporates three enhanced definition (ED) filter channels with third-order Butterworth characteristics. These filters are useful as digital-to-analog converter (DAC) reconstruction filters or as analog-to-digital converter (ADC) anti-aliasing filters supporting 480p/576p Y'P'BP'R and R'G'B' video. The THS7319 is also ideal for oversampled systems that produce standard-definition (SD) signals including CVBS, S-Video, 480i/576i Y'P'BP'R, Y'U'V', and R'G'B'.

The THS7319 is designed for dc-coupled inputs. To mitigate any DAC/encoder termination interaction, the input impedance is a very high 2.4 MΩ. The 150-mV output level shift allows for a full sync dynamic range at the output with a 0-V input that prevents sync crushing. The rail-to-rail output stage supports both ac and dc line driving.

The THS7319 is offered in a RoHS-compliant ultra-small MicrostarCSP 9-ball package.
