THS7314DR TI Video Amplifier | 8-SOIC | 3-Channel, 6th-Order SDTV Filter

Product Overview

The THS7314DR from Texas Instruments is a low-power, single-supply 3-channel integrated video buffer with a 6th-order SDTV reconstruction filter. It is designed for standard-definition video applications, providing excellent image quality with minimal external components. The device operates from a 2.7V to 5.5V supply and features a 3.4MHz filter suitable for SDTV (PAL/NTSC) signals. Each channel includes a 6th-order Butterworth filter and a 6dB gain buffer, enabling direct drive of video loads. The THS7314DR is available in an 8-pin SOIC package, making it ideal for space-constrained designs.
