Product details
Overview
SN10501DGN 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 error - enabling precision composite video distribution in broadcast and consumer electronics.
For engineers reviewing the SN10501DGN datasheet, SN10501DGN pinout, SN10501DGN application, or SN10501DGN equivalent, key selection criteria include its 50 MHz 0.1-dB flat bandwidth, ultralow HD2/HD3 distortion (–78 dBc/–85 dBc @ 5 MHz), PowerPAD™ thermal package for high-current drive (100 mA typ), and compatibility with ±5 V or single 5 V supplies in 75 Ω cable-drive topologies.
Technical Context
The SN10501DGN employs a voltage-feedback architecture with unity-gain stability and internal compensation, supporting both inverting and noninverting configurations up to G = 10. Its input stage operates with a common-mode range of VS− + 1.1 V to VS+ − 1.1 V, and its rail-to-rail output stage sustains >95 mA sourcing/sinking into 10 Ω loads while maintaining <0.09 Ω small-signal output impedance at 1 MHz.
Designed for 75 Ω video systems, it achieves <0.007° differential phase error under NTSC/PAL conditions with 150 Ω termination and supports multi-load drive (up to 3× 150 Ω) without gain flatness degradation - enabled by linear high-frequency output impedance and low crosstalk (<–90 dB).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (–3 dB) | 100 MHz at G = 2, RL = 150 Ω - supports full HD baseband video bandwidth without attenuation |
| 0.1-dB Flat Bandwidth | 50 MHz at G = 2, RL = 150 Ω - ensures minimal amplitude variation across NTSC/PAL luminance band |
| Slew Rate | 900 V/µs - enables clean 2 VPP square-wave reproduction up to ~57 MHz full-power bandwidth |
| Differential Gain Error | 0.007% at NTSC/PAL, RL = 150 Ω - preserves color fidelity in analog video transmission |
| Output Swing | ±4.5 V into 150 Ω - delivers full 2 VPP video signal across 75 Ω cable with 6 dB gain compensation |
| Harmonic Distortion | HD2 = –78 dBc, HD3 = –85 dBc @ 5 MHz, 2 VPP - meets broadcast-grade signal purity requirements |
| Quiescent Current | 14 mA per channel @ ±5 V - balances high-speed performance with moderate power consumption |
Pinout & Package
SN10501DGN uses an MSOP-8-PP (PowerPAD™) package with exposed thermal pad on underside, requiring solder connection to PCB ground plane for thermal integrity and rated 1.71 W dissipation at TA ≤ 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VOUT) | Amplifier output | Drives 75 Ω video load directly; rail-to-rail swing supports ±4.5 V into 150 Ω |
| 2 (IN−) | Inverting input | Accepts feedback network (e.g., 1.43 kΩ) for gain-setting; matched to IN+ for bias cancellation |
| 3 (IN+) | Noninverting input | DC-biased via resistor divider in single-supply video circuits; CM range = VS− + 1.1 V to VS+ − 1.1 V |
| 4 (VS−) | Negative supply | Connect to ground (single supply) or negative rail (dual supply); must be decoupled with 0.1 µF + 10 µF |
| 5 (NC) | No internal connection | Not bonded; leave unconnected or tie to ground only if required for mechanical stability |
| 6 (VS+) | Positive supply | Supports 3–15 V single or ±1.35–8 V dual; decouple identically to VS− |
| 7 (NC) | No internal connection | Not bonded; no electrical function |
| 8 (NC) | No internal connection | Not bonded; PowerPAD™ thermal pad occupies underside center - must be soldered to thermal plane |
Key Features
| Feature | Design Value |

IC Role / Device Role / Timing Role: High-fidelity buffer isolating DAC from cable capacitance and connector mismatch. Use Value: 100 MHz bandwidth and 900 V/µs slew rate prevent edge ringing on sharp video transitions (e.g., text overlays). | Use Scenario: Implementing 5-pole active low-pass filters in professional video equipment to suppress aliasing above 6 MHz. IC Role / Device Role / Timing Role: Unity-gain stable op-amp used in MFB or biquad filter topologies with precision external resistors/capacitors. Use Value: Low input bias current (0.9 µA max) and high open-loop gain (100 dB) ensure filter corner accuracy and stopband rejection. |
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 (520 MHz), but higher quiescent current (18 mA) and no rail-to-rail output | Better suited for pulse/video transient fidelity in test equipment; requires ±5 V and external level-shifting for 75 Ω drive | Select THS3201DR when >100 MHz small-signal BW or sub-ns settling is mandatory; avoid if rail-to-rail swing or low-power operation is required. |
| LMH6702MA | Similar 1.8 GHz GBW and 3000 V/µs slew rate, but fixed 200 mA IOUT and no PowerPAD™ thermal enhancement | Optimized for wideband ADC/DAC buffering; lacks differential gain/phase characterization for video standards | Choose LMH6702MA for general-purpose high-speed signal chain conditioning where video-specific distortion specs are not mandated. |
Compared with THS3201DR and LMH6702MA, SN10501DGN uniquely combines broadcast-grade differential gain/phase performance, rail-to-rail output, PowerPAD™ thermal management, and 14 mA quiescent current - making it the only option qualified for cost-sensitive, thermally constrained, standards-compliant video line driving.

FAQ
What is the maximum recommended supply voltage for SN10501DGN?
The absolute maximum supply voltage for SN10501DGN is ±8 V for dual supply or 16 V for single supply, per TI's Absolute Maximum Ratings table. However, the recommended operating range is ±1.35 V to ±8 V (dual) or 2.7 V to 16 V (single). Operating beyond ±8 V/16 V risks permanent damage, and sustained operation above 125°C junction temperature degrades long-term reliability.
Does SN10501DGN support single-supply operation with DC-coupled video inputs?
Yes, SN10501DGN supports DC-coupled single-supply operation when the input common-mode voltage is biased between VS− + 1.1 V and VS+ − 1.1 V. For a 5 V supply, this means input must stay within 1.1 V to 3.9 V. Figure 35 in the datasheet shows a verified circuit using resistor dividers and bypass capacitors to establish proper bias for composite video signals.
How does the PowerPAD™ thermal pad on SN10501DGN affect PCB layout?
The PowerPAD™ on SN10501DGN is an exposed copper thermal pad on the underside of the MSOP-8-PP package that must be soldered to a dedicated PCB ground plane with ≥4 thermal vias (0.3 mm diameter) to achieve rated 1.71 W power dissipation. Failure to connect it results in excessive junction temperature (>125°C), increased distortion, and potential device failure - per TI Technical Brief SLMA002.
Can SN10501DGN drive three 75 Ω video loads simultaneously?
Yes, SN10501DGN can drive up to three 75 Ω video loads (equivalent to 25 Ω total load) while maintaining <0.02% differential gain error and flat frequency response, as validated in Figures 16–18 of the datasheet. This is enabled by its linear high-frequency output impedance and 100 mA output current capability - confirmed under NTSC/PAL test conditions with 150 Ω termination per load.
What is the typical harmonic distortion performance of SN10501DGN at 10 MHz?
While datasheet harmonic distortion data is specified at 5 MHz (HD2 = –78 dBc, HD3 = –85 dBc), extrapolation from Figure 14 shows HD2 degrades to ≈ –65 dBc and HD3 to ≈ –72 dBc at 10 MHz under identical conditions (G = 2, 2 VPP, RL = 150 Ω). For 10 MHz-critical designs, SN10501DGN remains viable but THS3201DR offers superior high-frequency distortion performance.
