THS7372IPWR

The THS7372IPWR from Texas Instruments is a versatile 4-channel video amplifier designed for high-definition and standard-definition video signals. It incorporates one SDTV video amplifier for CVBS output and three fixed Full-HD 1080p60 filters for Y'/P'B/P'R, G'B'R', or Computer RGB outputs. Each channel features sixth-order low-pass filters, with the SD channel having a -3 dB cutoff at 9.5 MHz and the Full-HD channels at 72 MHz.

This amplifier supports versatile input biasing, allowing for DC-coupled operation with a 300-mV output shift or AC-coupled operation with sync-tip clamp or bias. It includes a built-in 6-dB gain (2 V/V) and operates from a +2.7-V to +5-V single supply. The rail-to-rail output swings within 100 mV of the rails, enabling flexible AC or DC output coupling and supporting the driving of two video lines per channel.

Fabricated using a complementary Silicon-Germanium (SiGe) BiCom3X process, the THS7372 offers low power consumption with a total quiescent current of 23.4 mA at 3.3 V. It also features a disabled supply current function of 0.1 µA. The device exhibits low differential gain and phase characteristics of 0.2% and 0.35°, respectively. It is supplied in a RoHS-compliant TSSOP-14 package, suitable for surface mounting.
