THS7314DG4

Video Amps And Modules Overview

The THS7314DG4 is a three-channel video amplifier from Texas Instruments, designed for standard-definition television (SDTV) applications. It integrates fifth-order filters and provides a fixed gain of 6 dB per channel. The device operates on a single power supply ranging from 2.85 V to 5.5 V, with a typical operating current of 16 mA. It features full-swing outputs capable of driving 70 mA per channel. The component is housed in an 8-pin SOIC package and supports surface-mount installation. It functions as an integrated filter amplifier suitable for buffering and signal conditioning in video processing circuits.

Video Amps And Modules Feature Summary

• Integrates third-order low-pass filters within each channel to support SDTV signal requirements.
• Provides fixed internal gain of 6 dB, eliminating the need for external feedback resistors.
• Features full-swing output stages capable of driving heavy loads directly.
• Supports single-supply operation with wide voltage range flexibility.

Video Amps And Modules Applications

• Standard-definition television (SDTV) video amplification
• Video buffer stages in consumer electronics
• Signal conditioning for composite video signals

Video Amps And Modules Procurement Notes

Verify the suffix 'DG4' indicates lead-free status and RoHS compliance when sourcing. Confirm the package type is SOIC-8 and check moisture sensitivity level requirements during storage and handling. Ensure the supplier provides valid datasheets matching the Texas Instruments part number to avoid counterfeit components.

Video Amps And Modules Selection Notes

Select this component for designs requiring integrated filtering and fixed gain in SDTV systems. Compare against the THS7316 if high-definition video bandwidth is required instead. Consider the THS7314DR variant if tape-and-reel packaging is preferred over tubes for automated assembly processes.

Video Amps And Modules Part Context

This part belongs to the THS731x family of video amplifiers from Texas Instruments. It shares architectural similarities with the THS7315 and THS7316 but is specifically optimized for standard-definition video frequencies. The DG4 suffix denotes a green, lead-free package compliant with environmental directives.

Video Amps And Modules Replacement Considerations

The THS7314DR is a functional equivalent with identical electrical characteristics but differs in packaging format. Verify pin compatibility before substitution.
