Product details
Overview
SN10503PWP from Texas Instruments is a triple-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 with ±5 V supplies - enabling high-fidelity composite video distribution in DVD players, imaging systems, and active filtering circuits.
For engineers reviewing the SN10503PWP datasheet, SN10503PWP pinout, SN10503PWP application, or SN10503PWP equivalent, key selection criteria include its triple-channel TSSOP-14 PowerPAD™ package, guaranteed 50 MHz 0.1 dB flat bandwidth, –78 dBc HD2 at 5 MHz, input common-mode range of VS− + 1.1 V to VS+ − 1.1 V, and thermal design requirements for the exposed thermal pad.
Technical Context
The SN10503PWP implements a unity-gain-stable voltage-feedback architecture with fully differential input stage and rail-to-rail output stage using complementary bipolar process. Its 120 MHz gain-bandwidth product supports stable operation at gains ≥1, while the 0.09 Ω output impedance and 90 dB crosstalk (f = 5 MHz) ensure minimal inter-channel interference in multi-channel video routing.
It operates from single 3–15 V or dual ±1.35–±8 V supplies, drawing only 14 mA per channel (typ) at 25°C. The device requires external biasing for single-supply video use, with input common-mode range constrained to 1.1 V above VS− and 1.1 V below VS+, and mandates thermal connection of the PowerPAD™ to PCB ground plane per SLMA002 guidelines.
Key Specifications

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 | Single-channel, 1.8 GHz bandwidth, current-feedback architecture; higher power (12 mA vs 14 mA/ch), no rail-to-rail output | Requires external level-shifting for video swing; better suited for RF IF buffering than baseband video | Select when >500 MHz bandwidth is required and triple-channel integration is not needed |
| LMH6703MF | Single-channel, 1.3 GHz bandwidth, current-feedback; 120 mA output drive but limited to ±2.5 V swing on ±5 V | Cannot deliver ±4.5 V into 150 Ω; unsuitable for standard 75 Ω video line driving without gain staging | Choose for ultra-high-speed non-video applications where rail-to-rail swing is not required |
Compared with THS3201DR and LMH6703MF, SN10503PWP uniquely combines triple-channel integration, rail-to-rail output, and broadcast-grade video specs (0.007% DG/DP) in one TSSOP-14 package - making it optimal for space-constrained, multi-signal video systems where fidelity and channel density are critical.

FAQ
What is the recommended power supply configuration for SN10503PWP in video applications?
The SN10503PWP supports both single-supply (3–15 V) and dual-supply (±1.35–±8 V) operation. For composite video line driving, ±5 V is recommended to achieve ±4.5 V output swing into 150 Ω. When using single 5 V, the input common-mode range is limited to 1.1 V to 3.9 V, requiring DC biasing networks such as those shown in Figure 38 of the SN10503PWP datasheet to maintain signal integrity.
Does SN10503PWP require external compensation for stability?
No, SN10503PWP is unity-gain stable and does not require external compensation capacitors. Its voltage-feedback architecture maintains phase margin across gains ≥1 with standard 1–2 kΩ feedback resistors. Layout best practices - including short traces, proper grounding, and 0.1 µF bypass capacitors at each VS+ and VS− pin - are sufficient to ensure stability in video-frequency applications.
How should the PowerPAD™ thermal pad on SN10503PWP be connected?
The exposed PowerPAD™ on the underside of the SN10503PWP must be soldered to a thermally robust PCB copper plane connected to VS− (GND). Per TI Technical Brief SLMA002, this connection is mandatory to achieve the rated 2.67 W power dissipation and prevent junction temperature exceedance. Failure to connect the pad may cause thermal shutdown or permanent damage during sustained video load conditions.
Can SN10503PWP drive three 75 Ω video loads simultaneously?
Yes, SN10503PWP maintains <0.014% differential gain and <0.011° differential phase error with up to three 150 Ω loads (equivalent to three 75 Ω cables in parallel), as verified in Figures 16–18 of the SN10503PWP datasheet. Its linear high-frequency output impedance enables predictable loading behavior without gain peaking or instability in multi-drop video distribution topologies.
What is the maximum output current capability of SN10503PWP per channel?
SN10503PWP delivers ±100 mA (typ) continuous output current per channel into 10 Ω loads, with guaranteed ±88 mA minimum at 85°C. This enables direct driving of multiple 75 Ω video lines or heavy capacitive loads (e.g., long cables) without external buffers, provided thermal management via the PowerPAD™ is implemented correctly.
