Product details
Overview
SN10501DGKG4 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, –78 dBc HD2 at 5 MHz, and ±4.5 V output swing into 150 Ω - enabling NTSC/PAL-compliant video distribution over 75 Ω coaxial cables in DVD players and imaging front-ends.
For engineers reviewing the SN10501DGKG4 datasheet, SN10501DGKG4 pinout, SN10501DGKG4 application, or SN10501DGKG4 equivalent, key selection criteria include its 50 MHz 0.1 dB flat bandwidth, differential gain/phase of 0.007%/0.007°, ±5 V dual-supply operation, MSOP-8 package thermal performance, and compatibility with 75 Ω source/load termination in broadcast-grade analog video paths.
Technical Context
The SN10501DGKG4 employs a voltage-feedback architecture with unity-gain stability and internal compensation. Its input stage operates with a common-mode range extending to within 1.1 V of each rail, while the rail-to-rail output stage sustains >100 mA sourcing/sinking capability into 150 Ω loads under ±5 V supply conditions.
It achieves video-grade linearity via low harmonic distortion (–78 dBc HD2, –85 dBc HD3), sub-0.01% differential gain error, and <0.01° differential phase shift - all verified at 5 MHz with 2 VPP output into 150 Ω, making it suitable for composite video buffering without color fidelity loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (–3 dB) | 100 MHz at G = 2, RL = 150 Ω - supports full NTSC/PAL baseband video spectrum without attenuation |
| 0.1 dB flat bandwidth | 50 MHz at G = 2 - ensures minimal amplitude variation across 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° at NTSC/PAL - preserves color saturation and hue accuracy in analog video systems |
| Output voltage swing | ±4.5 V into 150 Ω - drives standard 75 Ω video lines with 6 dB headroom after 2× gain and 75 Ω divider loss |
| Harmonic distortion | –78 dBc HD2, –85 dBc HD3 at 5 MHz - meets broadcast-grade THD requirements for SD video |
| Quiescent current | 14 mA per channel - enables low-power video buffer stages in portable DVD/CD-ROM players |
Pinout & Package
SN10501DGKG4 is housed in an 8-pin MSOP (DGK) package with exposed thermal pad (PowerPAD™). The package measures 3.0 mm × 3.0 mm × 1.0 mm and requires soldering the thermal pad to a PCB ground plane for reliable 125°C junction temperature operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN−) | Inverting input | High-impedance node (33 MΩ) for feedback network connection; requires bias-current cancellation resistor (649 Ω) when used in inverting configuration |
| 2 (IN+) | Noninverting input | DC-coupled input node with 1.1 V to VS−1.1 V common-mode range; accepts video baseband signals directly |
| 3 (VS−) | Negative supply rail | Connects to system ground or negative rail; must be decoupled with 0.1 µF ceramic capacitor near pin |
| 4 (VO) | Output | Rail-to-rail capable output driving 150 Ω loads; designed for 75 Ω source/load termination in video distribution circuits |
| 5 (NC) | No internal connection | Unbonded pin; must remain floating - no routing or grounding permitted |
| 6 (NC) | No internal connection | Unbonded pin; must remain floating - no routing or grounding permitted |
| 7 (VS+) | Positive supply rail | Accepts 3 V to 15 V single supply or ±1.35 V to ±8 V dual supply; requires 0.1 µF + 10 µF local decoupling |
| 8 (NC) | No internal connection | Unbonded pin; must remain floating - no routing or grounding permitted |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers ±4.5 V into 150 Ω on ±5 V supplies - matches 75 Ω video line requirements after 2× gain and resistive divider loss |
| Video-optimized linearity | 0.007% differential gain and 0.007° differential phase ensure NTSC/PAL color fidelity without post-processing correction |
| High output drive | Sustains 100 mA sourcing/sinking into 10 Ω loads - enables direct drive of multiple 75 Ω video outputs via star topology |
| Low distortion at 5 MHz | –78 dBc HD2 and –85 dBc HD3 meet SMPTE 253M broadcast linearity standards for SD video amplifiers |
| Thermally enhanced PowerPAD™ | Exposed die-pad reduces θJA to 260°C/W - enables stable operation at 125°C junction temperature with proper PCB copper area |

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 (12.5 mA/channel vs. 14 mA) and no rail-to-rail output | Used in RF-modulated video or high-speed test equipment where speed outweighs power and output swing constraints | Select THS3201DR only when >1 GHz small-signal bandwidth is required and ±5 V output swing is not needed |
| LMH6702MA | Wider 0.1 dB flat bandwidth (1.1 GHz), lower distortion (–85 dBc HD2), but requires external compensation and lacks integrated PowerPAD™ thermal solution | Favored in high-end broadcast gear requiring ultra-low group delay variation and wide dynamic range | Choose LMH6702MA for >500 MHz applications where layout complexity and thermal management are acceptable trade-offs |
Compared with THS3201DR and LMH6702MA, SN10501DGKG4 offers superior rail-to-rail output swing and integrated thermal management in MSOP-8, making it optimal for space-constrained, low-power, broadcast-compliant video line drivers where 100 MHz bandwidth suffices.

FAQ
What is the maximum operating supply voltage for SN10501DGKG4?
The SN10501DGKG4 supports a maximum supply voltage of ±8 V for dual-supply operation or 16 V for single-supply use. Absolute maximum ratings specify 16.5 V total supply differential; exceeding this risks permanent damage. Operation at ±5 V is typical for video applications, delivering optimal distortion performance and output swing.
Does SN10501DGKG4 support single-supply operation with DC-coupled video inputs?
Yes, SN10501DGKG4 supports single-supply operation down to 3 V, but its input common-mode range is limited to VS− + 1.1 V to VS+ − 1.1 V. For a 5 V supply, inputs must stay between 1.1 V and 3.9 V. DC-coupled video requires level-shifting circuitry to center the 0–1 V sync-blank range within this window.
How does the PowerPAD™ thermal pad on SN10501DGKG4 affect PCB layout?
The exposed thermal pad on SN10501DGKG4 must be soldered to a dedicated PCB copper pour connected to ground. TI specifies minimum 10 mm² pad area and thermal vias to inner ground planes. Failure to connect the PowerPAD™ raises junction temperature beyond 125°C, degrading distortion performance and reliability - especially critical at 100 mA output currents.
Can SN10501DGKG4 drive multiple 75 Ω video loads simultaneously?
Yes, SN10501DGKG4 maintains 0.007% differential gain and 0.007° differential phase with up to three 75 Ω loads due to its linear high-frequency output impedance. However, total load capacitance must remain below 100 pF; for longer cables or >3 loads, increase gain or add series termination to preserve stability and flatness.
What is the recommended feedback resistor value for SN10501DGKG4 in a G = 2 video driver?
Texas Instruments recommends Rf = 1.43 kΩ for G = 2 noninverting video driver configurations with SN10501DGKG4. This value balances bandwidth (50 MHz 0.1 dB flat), distortion (–78 dBc HD2), and output loading. Values below 1 kΩ increase noise and reduce bandwidth; values above 2 kΩ degrade slew rate and transient response.
