Product details
Overview
OPA3692ID from Texas Instruments is a triple, wideband, fixed-gain video buffer amplifier with independent disable control per channel. It delivers 225MHz bandwidth at G = +2, ±4.0V output swing, 190mA output current, and 5.1mA/ch quiescent supply current on ±5V supplies - enabling RGB line driving and single-supply ADC buffering in portable instrumentation and broadcast video systems.
For engineers reviewing the OPA3692ID datasheet, OPA3692ID pinout, OPA3692ID application, or OPA3692ID equivalent, key selection criteria include its internally trimmed gain accuracy (±0.3% typ at G = +2), high-frequency pinout optimized for video layout, low 150µA/ch disabled current, and guaranteed 0.1dB gain flatness to 120MHz - all validated across –40°C to +85°C.
Technical Context
The OPA3692ID uses a current-feedback architecture with internal 402Ω RF/RG resistor networks, enabling precise fixed gains of +2, +1, or –1 without external components. Its output stage delivers high slew rate (2000 V/µs min) and low crossover distortion while operating within 1V of either rail on +5V single supply.
Each channel features an independent DIS pin that places the output in high-impedance state with <150µA/ch supply current and 74dB off-isolation at 5MHz. The SO-16 package supports signal flow-through PCB routing, and thermal resistance is 100°C/W (θJA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (G = +2) | 225 MHz min - supports NTSC/PAL RGB signals up to 1080p60 with >0.1dB flatness to 120MHz |
| Output Current | ±190 mA min - drives three 75Ω video lines simultaneously with <0.17% differential gain error |
| Supply Current | 5.1 mA/ch typ at +25°C - total 15.3 mA for all channels on ±5V; drops to <450 µA total when disabled |
| Output Swing | ±3.9 V min into 100Ω - enables 2.8VPP RGB signal delivery on ±5V supplies with headroom margin |
| Disable Time | 1 µs typ - supports fast channel multiplexing in multi-ADC driver applications without signal interruption |
| Harmonic Distortion | –69 dBc 2nd-harmonic max at 5MHz/2VPP/100Ω - meets broadcast-grade video fidelity requirements |
| Differential Phase | 0.02° typ at NTSC/150Ω - preserves color timing integrity in analog video transmission |
Pinout & Package
OPA3692ID is housed in a 16-pin SOIC (SO-16) package with exposed pad not present; pinout follows TI's standard triple op amp layout optimized for video signal flow-through routing.

| 3, 7, 11 | DIS A/B/C | Active-low disable control; open or HIGH = normal operation; LOW = high-Z output + <150µA/ch current |
| 4, 12 | –VS | Negative supply rail; must be ≥ –6.5V; connects to ground in single-supply configurations |
| 8, 16 | +VS | Positive supply rail; supports +5V to +12V single or ±2.5V to ±6V dual operation |
| 13, 14, 15 | OUT A/B/C | Buffered outputs; capable of ±190mA drive into 100Ω with <0.12Ω closed-loop output impedance at 100kHz |
Key Features
| Feature | Design Value |
|---|---|

| Low-glitch enable/disable | Turn-on/off glitches limited to ±50mV/±20mV; enables clean switching in multiplexed ADC driver topologies |
| Single-supply operation | Delivers 3VPP output swing with >150MHz BW on +5V supply - eliminates need for negative rail in portable instruments |
| Thermal robustness | Specified over –40°C to +85°C with <0.13%/°C gain drift; θJA = 100°C/W enables reliable operation in dense video PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA3682ID | Lower bandwidth (180MHz G=+2), higher supply current (6.5mA/ch), no disable function | Lacks channel disable and has reduced gain flatness (80MHz 0.1dB); unsuitable for power-gated or multiplexed systems | Select OPA3682ID only if disable control and >200MHz bandwidth are unnecessary and cost is primary constraint |
| OPA3691IDR | Dual-channel version; identical AC specs but lacks third channel and DIS pin per channel | Requires two devices to match OPA3692ID's triple functionality; increases board area and BOM count | Choose OPA3691IDR only when system requires exactly two buffered channels and space allows dual-device layout |
Compared with OPA3682ID and OPA3691IDR, the OPA3692ID uniquely integrates three independent, disable-capable video buffers in one SO-16 package - reducing component count, PCB area, and inter-channel skew while enabling dynamic power management in portable and multi-channel video systems.

FAQ
What supply voltage ranges does the OPA3692ID support?
The OPA3692ID operates from ±2.5V to ±6V dual supplies or +5V to +12V single supply. At ±5V, it delivers 225MHz bandwidth and ±3.9V output swing into 100Ω. On +5V single supply, it achieves >150MHz bandwidth with 3VPP output swing - validated across –40°C to +85°C. Absolute maximum supply is ±6.5V.
How does the OPA3692ID achieve fixed gain without external resistors?
The OPA3692ID integrates precision 402Ω internal RF and RG resistors. For G = +2, the –IN pin is grounded; for G = +1, –IN is left open; for G = –1, –IN is connected to the output. Gain error is trimmed to ±0.3% max at +25°C with <0.13%/°C drift - eliminating external resistor tolerance and layout sensitivity in video applications.
What is the disable behavior of the OPA3692ID and how is it controlled?
Each channel of the OPA3692ID has an independent DIS pin. Pulling DIS LOW disables the amplifier, placing the output in high-impedance state and reducing supply current to <150µA/ch. Disable time is 1µs typ; enable time is 25ns typ. Open or HIGH on DIS enables normal operation. Off-isolation is 74dB at 5MHz, ensuring minimal feedthrough during disable.
Can the OPA3692ID drive 75Ω video loads directly, and what performance is guaranteed?
Yes - the OPA3692ID is characterized driving 75Ω loads. At NTSC conditions (150Ω load), it guarantees 0.07% differential gain error and 0.02° differential phase error. Output current is ±190mA min, supporting simultaneous drive of three 75Ω lines. Bandwidth remains >220MHz at G = +2 into 75Ω, with <0.2dB peaking at G = +1.
What package and thermal specifications apply to the OPA3692ID?
The OPA3692ID is supplied in a 16-pin SOIC (SO-16) package with θJA = 100°C/W. It is rated for –40°C to +85°C operation. No exposed thermal pad is present. The pinout supports flow-through routing for minimal video signal path length and crosstalk - critical for maintaining >200MHz bandwidth integrity in dense PCB layouts.
