Product details
Overview
SN10501DGK 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 over 75 Ω coaxial cables.
For engineers reviewing the SN10501DGK datasheet, SN10501DGK pinout, SN10501DGK application, or SN10501DGK equivalent, key selection criteria include its 50 MHz 0.1 dB flat bandwidth, ultralow HD2/HD3 distortion (–78 dBc/–85 dBc @ 5 MHz), rail-to-rail output stage, ±5 V or single 5 V supply operation, and MSOP-8 package compatibility with space-constrained video interface PCBs.
Technical Context
The SN10501DGK employs a voltage-feedback architecture with unity-gain stability and supports both inverting and noninverting configurations. 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 100 mA sourcing/sinking capability into 150 Ω loads while maintaining < 0.1 dB gain flatness up to 50 MHz.
Designed for 75 Ω video cable drive, it uses external 1.43 kΩ feedback resistors to achieve G = 2, compensating for the 6 dB loss across matched source/load terminations. Differential gain/phase performance is characterized per NTSC/PAL standards with 40 IRE ramps and validated under ±5 V and single 5 V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 100 MHz (–3 dB, G = 2, RL = 150 Ω): ensures full NTSC/PAL baseband and color subcarrier fidelity without roll-off. |
| 0.1 dB flat bandwidth | 50 MHz (G = 2, RL = 150 Ω): preserves luminance edge integrity and chroma timing accuracy in composite video signals. |
| Slew rate | 900 V/µs (G = 2, VO = ±2.5 VPP): prevents transient-induced distortion on fast sync pulses and sharp video edges. |
| Differential gain error | 0.007% (NTSC/PAL, RL = 150 Ω): maintains consistent color saturation across luminance levels in broadcast-grade video paths. |
| Output voltage swing | ±4.5 V (RL = 150 Ω, VS = ±5 V): delivers full 2 VPP video signal headroom after 6 dB cable attenuation compensation. |
| Harmonic distortion | HD2 = –78 dBc, HD3 = –85 dBc (f = 5 MHz, RL = 150 Ω): minimizes intermodulation artifacts in multi-tone video and test signal environments. |
| Supply range | ±5 V or single 5 V: enables drop-in integration into legacy dual-supply video systems or modern low-voltage embedded designs. |
Pinout & Package
SN10501DGK is housed in an 8-pin MSOP (DGK) package with exposed thermal pad (PowerPAD™), requiring connection to a PCB ground plane for thermal reliability. Pin assignments are verified per TI SLOS408B datasheet Figure 1 (top view).
| 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 with minimal clipping. |
| 2 (IN−) | Inverting input | Accepts feedback network (e.g., 1.43 kΩ) for precise G = 2 configuration in video line drivers. |
| 3 (IN+) | Noninverting input | Bias point for DC-coupled video; requires resistor divider to set common-mode voltage ≥ VS− + 1.1 V. |
| 4 (VS−) | Negative supply | Connect to ground (single supply) or negative rail; input common-mode range starts 1.1 V above this pin. |
| 5 (NC) | No internal connection | Must be left floating or grounded; no internal circuitry attached per TI pinout diagram. |
| 6 (VS+) | Positive supply | Accepts 3–15 V single or ±1.35–8 V dual; quiescent current remains ≤14 mA/channel across range. |
| 7 (NC) | No internal connection | Must be left floating or grounded; electrically isolated per TI package drawing. |
| 8 (NC) | No internal connection | Must be left floating or grounded; confirmed unconnected in DGK top-view schematic. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers ±4.5 V swing into 150 Ω with <1% THD, enabling full dynamic range utilization in 5 V systems. |
| 75 Ω video-optimized drive | Validated for composite video distribution with matched 75 Ω source/load termination and 1.43 kΩ feedback. |
| 0.007% / 0.007° differential gain/phase | Meets broadcast-grade NTSC/PAL specifications across temperature, ensuring stable color reproduction. |
| 900 V/µs slew rate | Prevents sync pulse overshoot and edge ringing in 525-line/625-line video waveforms. |
| Single-supply capable (3–15 V) | Operates from 5 V with input biasing networks (e.g., resistor dividers) to maintain valid common-mode range. |

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. | Preferred for ultra-high-speed pulse amplification (e.g., laser drivers), not optimized for 75 Ω video cable drive. | Select THS3201DR only when >200 MHz small-signal bandwidth is required and rail-to-rail output is unnecessary. |
| LMH6702MA | Lower distortion (HD3 = –92 dBc @ 5 MHz), same 100 MHz bandwidth, but requires ±5 V supply and lacks 0.1 dB flatness specification. | Better suited for instrumentation-grade signal chains where harmonic purity outweighs video-specific differential gain specs. | Choose LMH6702MA for lab equipment or test fixtures demanding lowest possible HD3, not broadcast video compliance. |
Compared with THS3201DR and LMH6702MA, SN10501DGK uniquely balances 50 MHz 0.1 dB flatness, 0.007% differential gain, rail-to-rail output, and 14 mA quiescent current - making it the only option qualified for cost-sensitive, space-constrained, broadcast-compliant video line driving in MSOP-8.

FAQ
What is the maximum operating supply voltage for SN10501DGK?
The SN10501DGK supports dual supplies up to ±8 V or a single supply up to 16 V. Absolute maximum ratings specify 16.5 V total supply voltage (VS+ to VS−), but recommended operation limits are ±8 V for dual supply and 16 V for single supply to ensure long-term reliability and specified AC performance.
Can SN10501DGK drive multiple 75 Ω video loads simultaneously?
Yes, SN10501DGK can drive up to three 75 Ω video loads with <0.02% differential gain error and <0.02° differential phase error, as validated in TI SLOS408B Figure 16–18. Its linear high-frequency output impedance enables stable multi-load distribution without external isolation buffers.
Does SN10501DGK require external compensation capacitors for stability?
No, SN10501DGK is unity-gain stable and does not require external compensation. TI's datasheet confirms unconditional stability with standard 1.43 kΩ feedback resistors and 75 Ω loads. However, proper power supply decoupling (0.1 µF ceramic + 10 µF tantalum per supply pin) is mandatory for video-bandwidth operation.
What is the input common-mode voltage range for SN10501DGK at ±5 V supply?
At ±5 V supply, the input common-mode voltage range for SN10501DGK is –3.9 V to +3.9 V (VS− + 1.1 V to VS+ − 1.1 V). This excludes the rails by 1.1 V, requiring bias networks for single-supply operation but providing robust rejection of supply noise in dual-supply video systems.
Is the PowerPAD™ thermal pad on SN10501DGK electrically connected?
No, the PowerPAD™ on SN10501DGK is thermally conductive only and must be soldered to a PCB ground plane for heat dissipation. TI documentation explicitly states it has no electrical connection - leaving it unconnected risks exceeding 125°C junction temperature and degrading distortion performance.
