Product details
Overview
SN10501DGNR from Texas Instruments is a single-channel, rail-to-rail output, high-speed voltage-feedback operational amplifier optimized for video line driving and low-distortion signal conditioning. It delivers 100 MHz (–3 dB) bandwidth at G = 2, 900 V/µs slew rate, ±4.5 V output swing into 150 Ω, and 0.007% differential gain / 0.007° differential phase (NTSC/PAL), enabling high-fidelity composite video distribution.
For engineers reviewing the SN10501DGNR datasheet, SN10501DGNR pinout, SN10501DGNR application, or SN10501DGNR equivalent, key selection criteria include its MSOP-8-PP PowerPAD™ package thermal performance, 50 MHz 0.1 dB flat bandwidth for broadcast-grade video, ±5 V or single 5 V supply operation, and verified 75 Ω cable drive capability with minimal SAG distortion.
Technical Context
The SN10501DGNR employs a unity-gain-stable voltage-feedback architecture with a rail-to-rail output stage capable of sourcing/sinking ≥100 mA. Its input stage features 33 MΩ input resistance and 1 pF common-mode capacitance, supporting wide common-mode range (VS− + 1.1 V to VS+ − 1.1 V) and high CMRR (94 dB min).
It operates across ±3 V to ±8 V dual supplies or 2.7 V to 16 V single supply, consuming only 14 mA quiescent current per channel. The integrated PowerPAD™ thermal pad in the DGN package requires PCB connection to a thermally dissipating plane to maintain junction temperature ≤125°C under full load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (–3 dB) | 100 MHz at G = 2, RL = 150 Ω - supports HD baseband video and fast transient response. |
| 0.1 dB Flat Bandwidth | 50 MHz at G = 2 - ensures amplitude fidelity across NTSC/PAL luminance and chrominance bands. |
| Slew Rate | 900 V/µs - enables clean 2 VPP square wave reproduction up to ~57 MHz full-power bandwidth. |
| Differential Gain / Phase | 0.007% / 0.007° - meets broadcast video specs for color fidelity over 0–5 MHz signal range. |
| Output Swing | ±4.5 V into 150 Ω - drives standard 75 Ω coaxial cables with 6 dB gain compensation topology. |
| Harmonic Distortion | HD2 = –78 dBc, HD3 = –85 dBc at 5 MHz - preserves signal integrity in multi-channel video systems. |
| Quiescent Current | 14 mA max per channel - enables low-power portable imaging and DVD-ROM analog output stages. |
Pinout & Package
The SN10501DGNR is housed in an 8-pin MSOP-8-PP (PowerPAD™) package with exposed thermal pad on underside, requiring solder connection to PCB copper pour for thermal management. Pin 1 is marked by dot; top view orientation matches TI's official DGN package drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused pin; must be left floating or tied to GND per layout best practice. |
| 2 (IN−) | Inverting input | High-impedance node (33 MΩ); requires matched termination in video inverting configurations. |
| 3 (IN+) | Non-inverting input | DC-biased reference point; used with RT resistor for single-supply level shifting. |
| 4 (VS−) | Negative supply rail | Connect to ground (single supply) or negative rail (dual supply); decoupling required. |
| 5 (NC) | No internal connection | Unused pin; no internal bond wire; leave unconnected. |
| 6 (VS+) | Positive supply rail | Accepts 2.7–16 V single or ±3–8 V dual; bypass with 0.1 µF ceramic near pin. |
| 7 (VOUT) | Amplifier output | Rail-to-rail capable; drives 75 Ω loads directly; PowerPAD™ enhances thermal dissipation. |
| 8 (NC) | No internal connection | Unused pin; electrically isolated; no PCB trace routing needed. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers ±4.5 V into 150 Ω with <1% clipping - eliminates need for level-shifting circuitry in 5 V systems. |
| 75 Ω video line driver compliance | Validated for direct 75 Ω source/load matching with 1.43 kΩ feedback resistors - reduces external component count. |
| Low differential distortion | 0.007% DG / 0.007° DP enables broadcast-quality NTSC/PAL signal transmission without post-correction. |
| PowerPAD™ thermal enhancement | θJC = 4.7 °C/W enables 1.71 W power dissipation at TA ≤25°C - sustains high output current without derating. |
| Single-supply operation support | Input common-mode range extends to VS− + 1.1 V - allows DC-coupled video biasing from 5 V rails. |
Applications
| Video Distribution System | DVD/CD-ROM Analog Output |
|---|---|
Use Scenario: Driving multiple 75 Ω coaxial cables from a single video source in set-top boxes or AV receivers. IC Role / Device Role / Timing Role: High-current, low-distortion buffer amplifier configured for G = 2 with 75 Ω series/shunt termination.

IC Role / Device Role / Timing Role: Low-noise (13 nV/√Hz), high-slew-rate amplifier interfacing sensor ADC drivers to video processors. Use Value: 900 V/µs slew rate prevents edge ringing on fast pixel clock transitions; 0.8 pA/√Hz input current noise minimizes dark current artifacts. | Use Scenario: Implementing 5th-order active low-pass filters for anti-aliasing in video digitization front-ends. IC Role / Device Role / Timing Role: High-GBW (120 MHz) op-amp in multiple-feedback (MFB) filter topology with precise pole placement. Use Value: 100 MHz bandwidth ensures filter group delay remains stable up to 20 MHz, preventing motion blur in high-frame-rate capture. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3201DR | Higher slew rate (4700 V/µs), wider bandwidth (1.8 GHz), but higher quiescent current (18 mA) and no rail-to-rail output. | Better suited for RF sampling and ultra-fast pulse amplification; not optimized for 75 Ω video linearity. | Choose THS3201DR only when >1 GHz small-signal BW is required and DC-coupled video swing is not critical. |
| LMH6702MA | Lower distortion (HD2 = –85 dBc), 1.7 GHz GBW, but requires ±5 V minimum supply and lacks PowerPAD™ thermal solution. | Preferred for high-resolution RGB video buffering where harmonic suppression dominates over thermal constraints. | Select LMH6702MA for multi-GHz analog signal chains where SN10501DGNR's 100 MHz BW is insufficient. |
Compared with THS3201DR and LMH6702MA, the SN10501DGNR uniquely balances broadcast-grade video linearity, 75 Ω drive capability, PowerPAD™ thermal efficiency, and single 5 V operation - making it optimal for cost-sensitive, space-constrained consumer video equipment.

FAQ
What is the maximum output current capability of the SN10501DGNR?
The SN10501DGNR delivers ≥100 mA sourcing and sinking current into 10 Ω loads, and maintains ±4.5 V output swing into 150 Ω. This high drive strength enables direct 75 Ω cable termination without external buffers, reducing bill-of-materials cost in video distribution designs using the SN10501DGNR.
Does the SN10501DGNR support single-supply operation?
Yes, the SN10501DGNR operates from a single 2.7 V to 16 V supply. Its input common-mode range extends from VS− + 1.1 V to VS+ − 1.1 V, allowing DC-coupled video biasing from 5 V rails. Application circuits in the datasheet demonstrate AC-coupled output and SAG correction topologies specifically validated for the SN10501DGNR.
What is the purpose of the PowerPAD™ thermal pad on the SN10501DGNR package?
The exposed thermal pad on the SN10501DGNR's MSOP-8-PP package serves as a primary heat path to the PCB. With θJC = 4.7 °C/W, it enables 1.71 W power dissipation at 25°C ambient. TI mandates soldering this pad to a thermally robust copper plane; failure to do so risks exceeding 125°C junction temperature and degrading SN10501DGNR distortion performance.
How does the SN10501DGNR achieve 0.007% differential gain in video applications?
The SN10501DGNR achieves 0.007% differential gain through precision trimming of its voltage-feedback core, low-input-bias-current design (≤3 µA), and linear high-frequency output impedance. These characteristics minimize gain variation across luminance (0–5 MHz) and chrominance (3.58 MHz) frequencies in NTSC/PAL signals - a specification rigorously measured and guaranteed for the SN10501DGNR.
Can the SN10501DGNR replace older video amplifiers like the THS4001 in existing designs?
The SN10501DGNR offers improved differential gain/phase (0.007% / 0.007° vs. THS4001's 0.02% / 0.1°), rail-to-rail output, and PowerPAD™ thermal performance. However, pinout differs: SN10501DGNR uses MSOP-8-PP with NC pins, while THS4001 uses SO-8. Direct replacement requires PCB layout revision; functional equivalence is confirmed for G = 2 video drive, but SN10501DGNR validation applies strictly to its own package and test conditions.
