The THS7376 is a low-power, 3-V to 5-V single-supply, four-channel, integrated video amplifier. The device incorporates one standard definition (SD) filter channel for CVBS video and three high-definition (HD) filter channels. The CVBS filter features a sixth-order filter and the HD channels feature eighth-order filters. These filters are useful as digital-to-analog converter (DAC) reconstruction filters or as analog-to-digital converter (ADC) antialiasing filters. The HD filters can be bypassed to support 1080p60 video or up to super extended graphics array (SXGA) RGB video. The device has flexible input coupling capabilities, and can be configured for either ac- or dc-coupled inputs. The 210-mV output level shift allows for a full sync dynamic range at the output with a 0-V input. The device's rail-to-rail output stage with 6-dB gain allows for both ac and dc line driving. The ability to drive two lines, or 75-Ω loads, allows for maximum flexibility as a video line driver. The 30.9-mA total quiescent current at 3.3 V and 0.1-µA disable mode makes the THS7376 an excellent choice for high-performance video applications. The THS7376 is available in a small TSSOP-14 package that is RoHS compliant. The device is pin-compatible with the THS7373 and THS7374 video filter amplifiers from Texas Instruments.
