THS7316D - 3-Channel HDTV Video Amplifier | Texas Instruments
料号： THS7316D ✓ 量产中THS7316D 概述
A video amplifier is a specialized analog amplifier that buffers and conditions composite or component video signals while preserving usable bandwidth and signal amplitude. The THS7316 belongs to the broader video-amplifier and signal-conditioning category, integrating three amplifier channels with fixed filtering into one device. This makes it useful in set-top boxes, television equipment, video processors, projectors, displays, and other systems that distribute or convert analog video signals.
The principal features of the THS7316D are its three-channel architecture, 6 dB voltage gain, 5th-order integrated filters, single-supply operation, and 43 MHz video bandwidth identified in the verified product data. The filter implementation helps remove unwanted high-frequency video components before they reach downstream circuitry. Its three-channel arrangement allows red, green, and blue video paths to be amplified consistently within one package, reducing the number of separate buffer devices required.
The device uses a low-power SiGe BiCom-III process and is intended for 3 V to 5 V single-supply systems. The verified distributor description identifies the THS7316 as a 3-channel integrated video buffer, while the Texas Instruments product page identifies the 5th-order filter and 6 dB gain functions. The 8-SOIC package is compatible with conventional surface-mount assembly and is suitable for compact consumer and industrial video equipment.
Typical applications include HDTV signal conditioning, RGB video distribution, video projection systems, television receivers, set-top-box video outputs, and industrial video interfaces. The integrated filtering is particularly useful where the source signal requires predictable bandwidth limiting before a display, encoder, scaler, or analog-to-digital conversion stage. The fixed 6 dB gain also provides a defined signal-conditioning function rather than requiring an external gain network for basic video buffering.
Designers should verify the complete electrical limits, decoupling requirements, output loading, and filter response in the manufacturer datasheet before layout release. Pay particular attention to the single-supply input range, required bypass capacitors, and the acceptable input and output signal levels. Because the available verified data does not provide the complete pin mapping or all parameter values, the PCB footprint and analog signal path should be checked against the official THS7316 documentation rather than inferred from distributor descriptions.
This page combines verified manufacturer and distributor information, source-backed technical context, and practical selection considerations for engineers evaluating the THS7316D. It also distinguishes verified attributes from parameters that remain to be confirmed in the datasheet, helping prevent assumptions about gain, bandwidth, filtering, or pin compatibility during component selection.

典型应用
THS7316D 适用于 6 应用s: HDTV Video Signal Conditioning, Television and Set-Top-Box Outputs, Video Projection Systems, RGB Video Distribution, Video Processor Interface, Industrial Video Monitoring.
HDTV Video Signal Conditioning
The THS7316D fits three-channel HDTV signal-conditioning paths because it combines three integrated video buffers, fifth-order filters, and 6 dB gain in one 8-SOIC device. Each channel can condition a parallel video signal while the integrated filters provide controlled high-frequency attenuation. Operating from a single 3 V to 5 V supply simplifies the rail architecture in television and display equipment, while 43 MHz bandwidth supports practical HDTV signal routing. The primary design check is the actual channel bandwidth and filter response, which must be taken from the manufacturer datasheet rather than inferred solely from the headline bandwidth.

Television and Set-Top-Box Outputs
Television receivers and set-top boxes commonly require consistent buffering of parallel RGB or component-video signals. The THS7316D provides three matched functional channels with integrated fifth-order filtering and 6 dB gain, reducing the need for separate buffer stages in these paths. Its 85 mA supply current and single 3 V to 5 V operation align with compact consumer-electronics power systems. Engineers should still verify output swing, load capability, bypass capacitors, and startup behavior against the THS7316 datasheet before committing a production layout.
推荐
Video Projection Systems
The THS7316D is suitable for conditioning video lines that feed projection electronics because it combines 6 dB gain with three integrated fifth-order filter channels. The fixed filtering can attenuate undesired high-frequency content before downstream scaling, conversion, or display-drive circuitry. A 43 MHz bandwidth figure supports HDTV-class routing, although the usable response at each channel must be checked with the specified filter and loading conditions. Its compact 8-SOIC format also helps reduce board area compared with three discrete buffered channels.
推荐
RGB Video Distribution
RGB distribution benefits from three channels that provide consistent amplification in one package. The THS7316D applies 6 dB gain to each video path and includes fifth-order filtering to control unwanted spectral content. Its 3 V to 5 V single-supply operation permits use in compact low-voltage equipment, while the 8-SOIC package supports conventional surface-mount assembly. When driving downstream cables or long PCB routes, engineers should confirm the output-current capability, capacitive-load limits, and termination strategy from the official datasheet.
推荐
Video Processor Interface
The THS7316D can serve as the analog output-conditioning stage of a video processor when three component-video channels require fixed gain and integrated filtering. Its 43 MHz bandwidth, 6 dB gain, and 85 mA current provide a defined operating point for HDTV signal paths. The fifth-order filters may simplify analog output conditioning compared with a collection of discrete buffers and passive networks. Input and output levels, DC offsets, channel-to-channel matching, and acceptable loading must be validated in the manufacturer documentation for the specific source and destination devices.
推荐
Industrial Video Monitoring
Industrial monitoring equipment can use the THS7316D to condition three analog video channels before they enter a recorder, encoder, or display interface. The integrated fifth-order filters provide a convenient bandwidth-control stage, while 6 dB gain can compensate for losses associated with routing and loading. Operation from a single 3 V to 5 V supply supports embedded industrial systems with constrained power budgets. For long cable runs, designers should verify the permitted loading, cable termination, channel bandwidth, and system-level signal integrity using the official THS7316 electrical characteristics.

- Verified 43 MHz video bandwidth （对比 THS7314D)
- Single-supply low-voltage operation （对比 THS7316DR)
设计说明
Place the required input, output, and supply bypass capacitors directly beside their associated THS7316D pins, following the manufacturer layout recommendations. High-speed video paths should use short traces and a continuous ground reference to minimize parasitic inductance and return-current discontinuities. Keep the three analog channels symmetric where channel-to-channel timing or gain matching matters, and avoid routing sensitive video lines adjacent to switching-supply nodes.
Treat the THS7316D's 43 MHz bandwidth, 6 dB gain, and fifth-order filters as a matched signal-conditioning chain rather than independent specifications. Account for source impedance, output loading, cable or PCB loss, and downstream input capacitance. Verify the complete channel response under the intended load because the usable video bandwidth can depend on termination and capacitive loading that are not captured by the headline bandwidth figure.
The verified supply-current figure is 85 mA, so confirm that the 3 V to 5 V source can support the device across temperature and load. Provide local bypass capacitance at the supply pins and keep the analog return path continuous. Do not raise the supply above the manufacturer maximum or substitute a regulator without checking the video amplifier's supply tolerances, startup behavior, and power-supply rejection expectations.
A common mistake is treating THS7316DR, THS7316DG4, or another related ordering code as automatically interchangeable without checking the device labeling and datasheet. Packaging suffix differences may indicate reel format, grade, or another orderable-device distinction. Likewise, a generic video amplifier with the same package is not necessarily a drop-in replacement because fifth-order filter response, gain, pin mapping, and output loading must all match.
