Product details
Overview
SN10502DR 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 bandwidth (–3 dB, G = 2), 900 V/µs slew rate, 0.007% differential gain, and ±4.5 V output swing into 150 Ω - enabling high-fidelity NTSC/PAL composite video distribution across matched 75 Ω coaxial cables.
For engineers reviewing the SN10502DR datasheet, SN10502DR pinout, SN10502DR application, or SN10502DR equivalent, this page provides verified technical context, SOIC-8 package layout, real-world video drive use cases, and validated alternative options for dual-channel high-speed amplification in industrial imaging, DVD/CD-ROM analog signal chains, and active filtering designs.
Technical Context
The SN10502DR implements a unity-gain-stable voltage-feedback architecture with fully differential input stage and rail-to-rail output stage capable of sourcing/sinking ≥100 mA per channel. Its 100-MHz small-signal bandwidth and 50-MHz 0.1-dB flat bandwidth are specified at G = 2 with 1.43 kΩ feedback resistors and 150 Ω load to ground under ±5 V supply.
It supports single-supply operation from 3 V to 15 V and dual-supply operation up to ±8 V, with quiescent current ≤14 mA per channel at 25°C. Input common-mode range extends from VS− + 1.1 V to VS+ − 1.1 V, and crosstalk between channels is –90 dB at 5 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 100 MHz at G = 2, RL = 150 Ω - ensures full NTSC/PAL baseband video fidelity without roll-off. |
| 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 fidelity in composite video transmission. |
| Output Swing | ±4.5 V into 150 Ω - drives standard 75 Ω video lines with 6 dB gain compensation via series/shunt termination. |
| Harmonic Distortion | HD2 = –78 dBc, HD3 = –85 dBc at 5 MHz - maintains signal integrity in low-noise analog front ends. |
| Supply Range | ±5 V (dual) or 5 V (single) - compatible with legacy video systems and modern low-voltage embedded platforms. |
| Quiescent Current | 14 mA per channel - balances performance and power efficiency in multi-channel video boards. |
Pinout & Package
SN10502DR is housed in an 8-pin SOIC (D) package with exposed thermal pad (PowerPAD™). Pin 1 is marked by notch or dot; top-view pinout follows TI standard for dual op-amps.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Drives first video load or filter stage; rail-to-rail swing supports DC-coupled video paths. |
| 1IN− | Channel 1 inverting input | Accepts feedback network (e.g., 1.43 kΩ) for precise gain setting in inverting configurations. |
| 1IN+ | Channel 1 noninverting input | Bias point for single-supply operation; requires DC reference (e.g., VS/2) for AC-coupled inputs. |
| VS− | Negative supply rail | Connect to ground (single supply) or negative rail (dual supply); PowerPAD must be soldered to PCB ground plane. |
| VS+ | Positive supply rail | Accepts 3–15 V (single) or ±1.35–±8 V (dual); decoupling (0.1 µF + 10 µF) required near pin. |
| 2OUT | Channel 2 output | Independent second video driver; crosstalk < –90 dB enables simultaneous RGB or Y/C channel routing. |
| 2IN− | Channel 2 inverting input | Configurable for gain-of-2 video distribution using matched 1.43 kΩ feedback and 75 Ω source termination. |
| 2IN+ | Channel 2 noninverting input | Used for noninverting gain stages or biasing; input common-mode range excludes rails by 1.1 V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers ±4.5 V swing into 150 Ω on ±5 V supplies - eliminates need for level-shifting in 75 Ω video interfaces. |
| Ultra-low distortion | –78 dBc HD2 / –85 dBc HD3 at 5 MHz enables high-SNR analog signal chains in imaging and optical sensing. |
| Video-optimized AC performance | 50 MHz 0.1-dB flat bandwidth and 0.007% differential gain meet broadcast-grade NTSC/PAL requirements. |
| High output drive capability | 100 mA sourcing/sinking per channel supports driving multiple 75 Ω loads or capacitive backplanes. |
| Thermally enhanced PowerPAD™ | SOIC-8-PP package includes exposed die paddle - requires PCB thermal plane connection to sustain 125°C junction limit. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel high-speed amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3202DR | Higher slew rate (2000 V/µs), wider bandwidth (500 MHz), but higher quiescent current (20 mA/ch) and no rail-to-rail output. | Better suited for pulse amplification or RF IF stages; less ideal for DC-coupled video due to limited output swing. | Select THS3202DR when >200 MHz bandwidth or sub-10 ns settling is required; avoid for 75 Ω video drive where rail-to-rail swing is critical. |
| LMH6629MF/NOPB | Lower distortion (HD2 = –92 dBc), similar bandwidth (800 MHz), but fixed-gain stable only at G ≥ 5 and no PowerPAD™ thermal enhancement. | Optimized for high-frequency instrumentation; not recommended for G = 2 video drive or thermally constrained SOIC layouts. | Choose LMH6629MF/NOPB for ultra-low-noise wideband preamplification; use SN10502DR for cost-sensitive, thermally demanding dual-video-channel designs. |
Compared with THS3202DR and LMH6629MF/NOPB, SN10502DR uniquely combines rail-to-rail output, 0.007% video-grade differential gain, SOIC-8 PowerPAD™ thermal performance, and G = 2 stability - making it the optimal choice for space-constrained, multi-channel analog video systems requiring broadcast-compliant fidelity.

FAQ
What is the maximum operating supply voltage for SN10502DR?
The SN10502DR supports dual-supply operation up to ±8 V and single-supply operation up to 16 V. Absolute maximum ratings specify ±16.5 V on VS+ and VS−, but continuous operation above ±8 V is not characterized and may degrade distortion or reliability. For robust video performance, TI recommends ±5 V or 5 V single supply per the datasheet test conditions used for all AC specifications including bandwidth and harmonic distortion.
Does SN10502DR require external compensation for G = 2 operation?
No, SN10502DR is unity-gain stable and does not require external compensation at G = 2. All published AC performance metrics - including 100 MHz bandwidth, 50 MHz 0.1-dB flatness, and –78 dBc HD2 - are measured at G = 2 with 1.43 kΩ feedback resistors and 150 Ω load. The voltage-feedback architecture ensures stability across gains ≥1 without added capacitors or resistor networks.
Can SN10502DR drive a 75 Ω cable directly without external termination resistors?
No - SN10502DR must be used with external 75 Ω series and shunt resistors to achieve proper 75 Ω source and load matching. As shown in Figure 36 of the datasheet, a G = 2 configuration with 1.43 kΩ feedback and 75 Ω source termination delivers net gain of 1 into the cable. Direct connection causes reflections, gain error, and degraded differential phase due to impedance mismatch.
Is the PowerPAD™ thermal pad on SN10502DR electrically connected internally?
No, the PowerPAD™ on SN10502DR is a thermally conductive, electrically isolated copper slug attached to the die underside. It must be soldered to a dedicated PCB thermal plane tied to VS− (ground in single-supply systems) for effective heat dissipation. Leaving it unconnected risks exceeding the 125°C maximum junction temperature during sustained 100 mA output current operation.
What is the input common-mode voltage range for SN10502DR at 5 V single supply?
At 5 V single supply, the input common-mode voltage range for SN10502DR is specified as VS− + 1.1 V to VS+ − 1.1 V, i.e., 1.1 V to 3.9 V. This excludes the supply rails by 1.1 V - meaning the device cannot accept input signals at ground or 5 V. For AC-coupled video inputs, a VS/2 (2.5 V) bias must be applied to the noninverting inputs via resistive divider or reference IC to keep signals within this valid range.
