Product details
Overview
THS7316DG4 from Texas Instruments is a 3-channel HDTV video amplifier with integrated 5th-order 36-MHz Butterworth low-pass filters, 6-dB fixed gain (2 V/V), rail-to-rail output stage, and support for DC- or AC-coupled inputs. It operates from a single 3-V to 5-V supply, draws only 18.3 mA at 3.3 V, and drives dual 75-Ω video lines per channel - ideal for Y'P'BP'R 720p/1080i, G'B'R', VGA/SVGA/XGA signal buffering in set-top boxes and portable video systems.
For engineers reviewing the THS7316DG4 datasheet, THS7316DG4 pinout, THS7316DG4 application, or THS7316DG4 equivalent, key selection considerations include its 36-MHz filter bandwidth, ±0.1% differential gain/phase accuracy, 30 dB attenuation at 74 MHz, SOIC-8 package compatibility, and flexible input biasing (DC-shifted or sync-tip clamp) for HDMI source output stages, broadcast encoder interfaces, and USB-powered video transmitters.
Technical Context
The THS7316DG4 implements a modified 5th-order Butterworth filter optimized for DAC reconstruction and ADC anti-aliasing in high-definition video paths. Its SiGe BiCom-III process enables low distortion (–70 dB THD), 67 dB SNR, and <0.3 ns channel-to-channel delay across all three channels.
Input configuration supports both DC-coupled operation with internal +140-mV level shift and AC-coupled operation with transparent sync-tip clamp - eliminating clipping on sync pulses while maintaining full dynamic range. The rail-to-rail output stage delivers >3.0 V swing into 75 Ω at 3.3 V, enabling direct drive of legacy CVBS or component video loads without external level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Filter bandwidth | 36 MHz (–3 dB); ensures full passband for 1080i/720p Y'P'BP'R and VGA signals without aliasing. |
| Gain | 6 dB (2 V/V) fixed; eliminates need for external gain-setting resistors and simplifies layout. |
| Differential gain/phase | 0.1% / 0.1°; preserves color fidelity in broadcast-grade video transmission. |
| Quiescent current | 18.3 mA at 3.3 V; enables USB-powered and battery-operated portable video applications. |
| Output swing | 3.0 V into 75 Ω at 3.3 V supply; supports driving two parallel 75-Ω lines per channel. |
| Supply range | 3 V to 5 V single supply; compatible with common logic rails and avoids dual-supply complexity. |
| Channel crosstalk | –61 dB at 1 MHz; prevents color bleeding between Y', P'B, and P'R channels in component video systems. |
Pinout & Package
THS7316DG4 is housed in an RoHS-compliant SOIC-8 (D) package with standard 1.27-mm pitch and 4.9-mm × 3.9-mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CH.1 IN (Pin 1) | Video input – Channel 1 | Accepts Y' (luma), G', or R' signal; supports DC-coupled (with 140-mV shift) or AC-coupled (sync-tip clamp) operation. |
| CH.2 IN (Pin 2) | Video input – Channel 2 | Accepts P'B, B', or G' signal; identical biasing flexibility as Pin 1; independent channel operation. |
| CH.3 IN (Pin 3) | Video input – Channel 3 | Accepts P'R, R', or B' signal; fully matched performance to Pins 1–2 for balanced component video routing. |
| +Vs (Pin 4) | Positive power supply | Connects to 3 V–5 V rail; requires local 0.1 µF decoupling capacitor for stability. |
| GND (Pin 5) | Ground reference | Common return for all internal circuitry; must be low-impedance connection to minimize noise coupling. |
| CH.3 OUT (Pin 6) | Video output – Channel 3 | Drives 75-Ω load directly; rail-to-rail swing allows AC or DC coupling to downstream receivers. |
| CH.2 OUT (Pin 7) | Video output – Channel 2 | Matched output drive capability and timing to Pin 6; <0.3 ns skew vs. other channels ensures pixel-aligned video. |
| CH.1 OUT (Pin 8) | Video output – Channel 1 | Primary luma or green channel output; same electrical specs as Pins 6–7; flow-through pinout simplifies PCB routing. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 5th-order LPF | 36-MHz Butterworth response provides sharp roll-off (30 dB @ 74 MHz) for clean HDTV reconstruction without external components. |
| Rail-to-rail output stage | Swings within 100 mV of rails into 75 Ω, enabling full-swing video drive without clamping diodes or level shifters. |
| DC + 140-mV input shift | Prevents sync pulse clipping at 0-V input by shifting output baseline to ~280 mV, preserving AGC loop integrity in receivers. |
| Sync-tip clamp mode | Active DC restoration loop clamps sync tip to 0 V without affecting active video; immune to overshoot via internal 80-ns LPF. |
| Low quiescent power | 18.3 mA total at 3.3 V enables thermal-constrained designs like dongles, capture cards, and embedded media players. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-channel video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS7314DR | 2-channel version; no CH.3 IN/OUT; identical filter/gain specs per channel. | Suitable only for dual-output systems (e.g., Y/C S-Video), not full Y'P'BP'R or RGB. | Select THS7314DR when only two video channels are required to reduce cost and footprint. |
| LMH6738MA/NOPB | Single-channel, wideband (850-MHz GBW) op-amp; no integrated filter or level shift; requires external components. | Used in custom high-speed analog front-ends where programmable bandwidth or variable gain is needed. | Choose LMH6738MA/NOPB only when design requires >100-MHz bandwidth or non-standard gain configurations. |
Compared with THS7316DG4, THS7314DR reduces channel count but retains identical per-channel performance and filtering, while LMH6738MA/NOPB offers higher bandwidth at the cost of increased design complexity, external component count, and power consumption - making THS7316DG4 optimal for production-ready HDTV/component video buffering.

FAQ
What video standards does the THS7316DG4 support?
The THS7316DG4 supports HDTV formats including Y'P'BP'R 720p and 1080i, G'B'R' (R'G'B'), and computer video standards VGA, SVGA, and XGA. Its 36-MHz filter bandwidth and 0.1% differential gain/phase meet SMPTE 293M and VESA DPM v1.0 requirements for broadcast and graphics applications. THS7316DG4 is not intended for SDTV-only use cases where lower-cost alternatives suffice.
Can the THS7316DG4 operate from a 3.3-V supply?
Yes, the THS7316DG4 is fully specified for 3.3-V single-supply operation, drawing only 18.3 mA quiescent current and delivering 3.0 V output swing into 75 Ω. Electrical characteristics including 36-MHz bandwidth, 6-dB gain, and –61 dB crosstalk are guaranteed across the full –40°C to +85°C temperature range at 3.3 V. THS7316DG4 maintains rail-to-rail output performance without degradation at this voltage.
Does the THS7316DG4 require external passive components for basic operation?
No, the THS7316DG4 integrates all critical functions - 5th-order filter, 6-dB gain, rail-to-rail output stage, and input biasing - eliminating the need for external resistors or capacitors in standard configurations. Only two mandatory external components are required: a 0.1-µF ceramic decoupling capacitor on +Vs and a 0.1-µF AC-coupling capacitor per input when using sync-tip clamp mode. THS7316DG4 achieves full functionality with minimal external BOM.
How does the THS7316DG4 handle sync pulse integrity in DC-coupled video paths?
The THS7316DG4 incorporates a +140-mV internal input level shift that raises the output baseline to ~280 mV when 0-V sync tip is applied, preventing transistor saturation and preserving horizontal/vertical sync amplitude for receiver AGC loops. This feature ensures no clipping occurs on sync pulses while maintaining full video swing - a critical requirement for broadcast compliance. THS7316DG4 achieves this without external bias networks or clamping diodes.
Is the THS7316DG4 pin-compatible with other members of the THS73xx family?
The THS7316DG4 shares the same SOIC-8 pinout and functional mapping with THS7314 (2-channel) and THS7353 (5-channel), enabling scalable design reuse across product tiers. However, channel count and internal filter tuning differ: THS7314 lacks CH.3 IN/OUT, and THS7353 adds two more channels with identical per-channel specs. THS7316DG4 is not pin-compatible with non-THS73xx video amplifiers due to unique sync-tip clamp and level-shift circuitry.
