Product details
Overview
SN10502DGKR from Texas Instruments is a dual-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 small-signal bandwidth (–3 dB, G = 2), 900 V/µs slew rate, ±4.5 V output swing into 150 Ω, –78 dBc HD2 at 5 MHz, and 0.007% differential gain - enabling high-fidelity composite video distribution in broadcast, DVD, and imaging systems.
For engineers reviewing the SN10502DGKR datasheet, SN10502DGKR pinout, SN10502DGKR application, or SN10502DGKR equivalent, key selection criteria include its dual-channel MSOP-8 footprint, rail-to-rail output swing under ±5 V supply, 50 MHz 0.1 dB flat bandwidth for NTSC/PAL compliance, crosstalk < –90 dB at 5 MHz, and thermal performance validated up to 85°C ambient with PowerPAD™-enhanced MSOP-8 package.
Technical Context
The SN10502DGKR implements a unity-gain-stable voltage-feedback architecture with fully differential input stage and Class-AB rail-to-rail output stage. Its 100 MHz bandwidth and 900 V/µs slew rate support fast transient response in video drive circuits, while the 33 MΩ input resistance and 1 pF common-mode input capacitance minimize loading on source impedances.
Designed for operation from ±3 V to ±8 V dual supplies or 3 V to 16 V single supply, it maintains 50 MHz 0.1 dB flatness into 150 Ω loads with 1.43 kΩ feedback resistors. Channel-to-channel crosstalk is –90 dB at 5 MHz, confirming isolation critical for dual-video-path applications like RGB or Y/C separation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 100 MHz (–3 dB, G = 2, RL = 150 Ω) - supports full HD baseband video without attenuation |
| 0.1 dB flat bandwidth | 50 MHz (G = 2, RL = 150 Ω) - preserves luminance/chrominance fidelity in NTSC/PAL signals |
| Slew rate | 900 V/µs (G = 2, VO = ±2.5 VPP) - ensures distortion-free reproduction of fast video edges |
| Differential gain / phase | 0.007% / 0.007° (NTSC/PAL, RL = 150 Ω) - meets broadcast-grade color accuracy requirements |
| Output voltage swing | ±4.5 V (RL = 150 Ω, VS = ±5 V) - delivers full rail-to-rail dynamic range into standard video loads |
| Crosstalk | –90 dB (f = 5 MHz, channel-to-channel) - prevents interference between dual video paths |
| Harmonic distortion | HD2 = –78 dBc, HD3 = –85 dBc (5 MHz, RL = 150 Ω) - enables clean signal chain integration before ADCs |
Pinout & Package
SN10502DGKR is housed in an 8-pin MSOP package (DGK) with exposed thermal pad (PowerPAD™), measuring 3.0 mm × 3.0 mm × 1.0 mm. The thermal pad must be soldered to a PCB copper pour for reliable power dissipation at TJ ≤ 125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Drives 75 Ω video load directly; rail-to-rail swing supports AC-coupled or DC-coupled video interfaces |
| 1IN− | Channel 1 inverting input | Accepts feedback network (e.g., 1.43 kΩ) for gain-setting; matched impedance critical for video termination |
| 1IN+ | Channel 1 non-inverting input | Bias point for single-supply operation; requires DC bias network (e.g., resistor divider to VS/2) |
| VS− | Negative supply rail | Connects to ground (single supply) or negative rail (dual supply); input common-mode range starts at VS− + 1.1 V |
| VS+ | Positive supply rail | Supports 3–16 V single or ±3–±8 V dual; quiescent current 14 mA/channel at ±5 V |
| 2OUT | Channel 2 output | Independent output with identical specs to 1OUT; enables dual-path video (e.g., Y + C or R + G) |
| 2IN− | Channel 2 inverting input | Separate feedback path per channel; no internal connection to Channel 1 |
| 2IN+ | Channel 2 non-inverting input | Independent bias node; allows independent DC operating points for each channel |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers ±4.5 V into 150 Ω at ±5 V supply - eliminates need for level-shifting in 75 Ω video distribution |
| Low differential distortion | 0.007% DG / 0.007° DP enables broadcast-compliant NTSC/PAL signal integrity without post-correction |
| High output drive | 100 mA sourcing/sinking capability supports driving multiple 75 Ω loads or capacitive cables up to several feet |
| Thermally enhanced MSOP | PowerPAD™ package reduces θJA to 260°C/W - sustains 14 mA/channel operation at 85°C ambient |
| Wide supply range | Operates from 3 V to 16 V single supply or ±3 V to ±8 V dual - simplifies integration into legacy and modern video systems |

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 |
|---|---|---|---|
| THS3202DR | Higher slew rate (1700 V/µs), wider bandwidth (500 MHz), but higher quiescent current (18 mA/channel) and no rail-to-rail output | Preferred for ultra-high-speed analog front-ends requiring >200 MHz bandwidth; unsuitable for rail-limited 75 Ω video loads | Select THS3202DR only when bandwidth >250 MHz is required and supply headroom permits non-rail-to-rail swing |
| LMH6702MA | Wider 0.1 dB flat bandwidth (120 MHz), lower distortion (–85 dBc HD2), but fixed-gain stable only at G ≥ 5 and no PowerPAD™ package | Better suited for fixed-gain, high-fidelity post-processing stages; lacks dual-channel integration and thermal robustness for compact video modules | Choose LMH6702MA for single-channel, high-precision gain blocks where layout space allows SOIC-8 and thermal management is less constrained |
Compared with THS3202DR and LMH6702MA, SN10502DGKR uniquely balances dual-channel integration, rail-to-rail output, 50 MHz video-flat bandwidth, and thermally enhanced MSOP packaging - making it optimal for space-constrained, multi-path video systems requiring broadcast-grade linearity without external level-shifting.

FAQ
What is the maximum operating temperature for SN10502DGKR?
The SN10502DGKR has a maximum junction temperature of 150°C, but continuous operation above 125°C degrades long-term reliability and increases distortion. With its MSOP-8 PowerPAD™ package and θJA = 260°C/W, SN10502DGKR supports full-spec operation up to 85°C ambient when properly heatsinked to PCB copper.
Can SN10502DGKR operate from a single 5-V supply?
Yes, SN10502DGKR operates from 3 V to 16 V single supply. For 5 V operation, bias the non-inverting inputs to 2.5 V (VS/2) using a resistor divider, and ensure input signals remain within 1.1 V to 3.9 V common-mode range. Output swing reaches 0.5 V to 4.5 V into 150 Ω, supporting standard video levels.
Does SN10502DGKR require external compensation for stability?
No, SN10502DGKR is unity-gain stable and does not require external compensation. It maintains phase margin >60° across all gains ≥1 with standard 1.43 kΩ feedback resistors and 150 Ω loads. Layout best practices (short traces, local 0.1 µF decoupling at VS+ and VS−) ensure stability in video applications.
How does SN10502DGKR handle multiple 75 Ω video loads?
SN10502DGKR maintains <0.02% differential gain error with up to three 75 Ω loads due to its linear high-frequency output impedance and 100 mA output drive. Each channel independently drives one 75 Ω load; for >1 load per channel, increase gain to compensate for cable loss, verified in Figure 37 of the datasheet.
Is the PowerPAD™ thermal pad on SN10502DGKR electrically connected?
No, the PowerPAD™ on SN10502DGKR is a thermal-only pad with no electrical connection. It must be soldered to a dedicated PCB thermal plane tied to VS− (ground in single-supply configurations) to achieve rated power dissipation and prevent junction temperature exceedance beyond 125°C.
