THS7373 is a low-power, single-supply, 3-V to 5-V, 720p/1080i/1080p30, or G’B’R’ (R’G’B’) four-channel integrated video buffer. It incorporates one standard-definition (CVBS) and three high-definition (HD) filter channels. All filters feature sixth-order Butterworth characteristics that are useful as digital-to-analog converter (DAC) reconstruction filters or as analog-to-digital converter (ADC) anti-aliasing filters. The HD filters can be bypassed to support 1080p60 video or up to quad extended graphics array (QXGA) RGB video. As part of the THS73 series, THS7373 is a very versatile video buffer that is well suited for a wide range of applications.
The THS7373 is a low‑power, single‑supply video amplifier that provides one standard‑definition (CVBS) channel and three high‑definition channels. Each channel includes a sixth‑order Butterworth low‑pass filter, and the device offers a built‑in 6‑dB (2 V/V) gain with rail‑to‑rail output capability.
Typical specifications include a supply voltage range of 3 V to 5 V, a quiescent current of 16.2 mA at 3.3 V, and operation in a TSSOP‑14 package. The part is suited for set‑top‑box video buffering, Blu‑Ray and DVD‑R output buffering, and other low‑power video applications.
