DESCRIPTION
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.
