Product details
Overview
SN10501DGKR 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 DVD players, imaging front-ends, and active filter stages.
For engineers reviewing the SN10501DGKR datasheet, SN10501DGKR pinout, SN10501DGKR application, or SN10501DGKR equivalent, key selection criteria include its 50 MHz 0.1-dB flat bandwidth for NTSC/PAL fidelity, ±5 V or single 5 V supply operation, MSOP-8 thermal performance with PowerPAD™, and verified 75 Ω cable drive capability without external level-shifting circuitry.
Technical Context
The SN10501DGKR 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 features 33 MΩ input resistance and 1 pF common-mode capacitance, while the rail-to-rail output stage sustains 100 mA sourcing/sinking into 150 Ω loads at ±5 V supplies.
Designed for wideband video signal chains, it maintains <0.01% differential gain/phase error under 40 IRE NTSC ramp conditions, achieves –78 dBc HD2 and –85 dBc HD3 at 5 MHz, and operates across –40°C to +85°C with 14 mA typical quiescent current per channel - all within a thermally enhanced MSOP-8-PP package.
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 - ensures minimal amplitude variation 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 error | 0.007% at NTSC, RL = 150 Ω - preserves color fidelity in analog video transmission |
| Output voltage swing | ±4.5 V into 150 Ω - drives standard 75 Ω coaxial cables with 6 dB gain compensation topology |
| Quiescent current | 14 mA per channel at ±5 V - balances speed and power for portable and embedded video systems |
| Input offset voltage | ≤30 mV max - minimizes dc error in dc-coupled video paths without trimming |
Pinout & Package
SN10501DGKR is housed in an 8-pin MSOP package with exposed thermal pad (MSOP-8-PP, TI's PowerPAD™ variant). The exposed pad must be soldered to a PCB thermal plane for reliable operation above 85°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VOUT) | Amplifier output | Delivers rail-to-rail swing; requires 0.1 µF local bypass to VS−/VS+ and series 75 Ω for 75 Ω cable termination |
| 2 (IN−) | Inverting input | Accepts feedback network (e.g., 1.43 kΩ); bias current cancellation resistor required when used in inverting mode |
| 3 (IN+) | Noninverting input | DC-biased to mid-supply in single-ended video configs; accepts AC-coupled video source via 10 µF capacitor |
| 4 (VS−) | Negative supply | Connect to ground (single supply) or negative rail; decouple with 0.1 µF + 10 µF near pin |
| 5 (NC) | No internal connection | Not bonded; leave unconnected or tie to ground only if required by layout EMI mitigation |
| 6 (VS+) | Positive supply | Supports 3 V to 15 V single or ±1.35 V to ±8 V dual; decouple identically to VS− |
| 7 (NC) | No internal connection | Not bonded; no electrical function - avoid routing signals underneath |
| 8 (NC) | No internal connection | Thermal pad connection point; must be soldered to ≥1 cm² copper pour for thermal reliability |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Swings to within 500 mV of either rail into 150 Ω - eliminates need for level-shifting in 5 V video systems |
| Ultra-low distortion | –78 dBc HD2 / –85 dBc HD3 at 5 MHz - preserves chroma signal integrity in composite video |
| 75 Ω video drive ready | Validated for direct 75 Ω cable drive with 1.43 kΩ feedback resistors - reduces BOM count vs discrete termination |
| PowerPAD™ thermal enhancement | θJC = 4.7°C/W - enables 1.71 W power dissipation at TA = 25°C when pad is connected to thermal plane |
| Single-supply compatibility | Operates from 5 V with input common-mode range of 1 V to 4 V - supports DC-coupled video amplification |
Applications
| Video Distribution Systems | DVD/CD-ROM Analog Output Stage |

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-amplifier or RF IF stages; not optimized for 75 Ω video cable drive or differential gain specs | Choose THS3201DR only when >200 MHz small-signal BW is mandatory and dc-coupled output swing is not required |
| LMH6702MA | Lower distortion (–92 dBc HD3), wider 0.1-dB flatness (120 MHz), but requires external VOS trim and lacks integrated PowerPAD™ | Preferred for test equipment or broadcast gear where ultimate linearity outweighs board space and thermal constraints | Select LMH6702MA when differential phase must stay below 0.003° and thermal management is handled via heatsink rather than PCB copper |
Compared with THS3201DR and LMH6702MA, SN10501DGKR provides the optimal balance of video-specific fidelity (0.007% DG/DP), 75 Ω drive readiness, rail-to-rail output, and MSOP-8 thermal efficiency - making it the default choice for cost-sensitive, space-constrained consumer video designs.

FAQ
What is the maximum recommended supply voltage for SN10501DGKR?
The absolute maximum supply voltage for SN10501DGKR is ±8 V for dual supply or 16 V for single supply, but the recommended operating range is ±5 V or 5 V. Exceeding ±8 V risks permanent damage per TI's Absolute Maximum Ratings table; operation at 15 V is permitted only with strict thermal management due to increased junction temperature rise.
Does SN10501DGKR support true single-supply operation with ground-referenced inputs?
Yes, SN10501DGKR supports true single-supply operation: its input common-mode range extends from 1 V to 4 V with a 5 V supply, allowing direct connection of AC-coupled video sources referenced to ground. However, the noninverting input must be biased to ≥1 V (e.g., via resistor divider to 2.5 V) to remain within spec - it does not accept inputs at ground potential.
How is the PowerPAD™ thermal pad on SN10501DGKR connected for optimal performance?
The exposed thermal pad on SN10501DGKR (Pin 8) must be soldered to a dedicated PCB copper pour of ≥1 cm² connected to ground or a low-impedance thermal plane. TI specifies θJC = 4.7°C/W only when the pad is fully soldered; omitting this connection reduces power dissipation capability from 1.71 W to ≤685 mW and risks thermal shutdown above 85°C ambient.
Can SN10501DGKR drive three 75 Ω video loads simultaneously?
Yes, SN10501DGKR can drive three 75 Ω video loads simultaneously while maintaining <0.014% differential gain and <0.011° differential phase error, as validated in TI's Figure 16–18. This is enabled by its linear high-frequency output impedance and 100 mA output drive - no external current boosters are needed for short-run multi-drop video distribution.
What feedback resistor value is required for 2× gain in a 75 Ω video system using SN10501DGKR?
For 2× gain in a standard 75 Ω video system, SN10501DGKR uses RF = 1.43 kΩ with RG = 1.43 kΩ in noninverting configuration, as shown in TI's Figure 36. This achieves precise 6 dB net gain to compensate for the 75 Ω source/load divider, while maintaining 50 MHz 0.1-dB flatness and <0.007% differential gain error.
