Product details
Overview
OPA3692IDRG4 from Texas Instruments is a triple, wideband, fixed-gain video buffer amplifier with disable control, designed for RGB line driving and ADC input buffering. It delivers 225MHz bandwidth at G = +2, ±4.0V output swing, 190mA output current, and operates on ±2.5V to ±6V or +5V to +12V supplies - enabling high-fidelity analog video signal conditioning in compact, power-sensitive systems.
For engineers reviewing the OPA3692IDRG4 datasheet, OPA3692IDRG4 pinout, OPA3692IDRG4 application, or OPA3692IDRG4 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed application use cases, and two rigorously cross-checked alternative parts - all grounded in TI's SBOS228E production data sheet and official ordering documentation.
Technical Context
The OPA3692IDRG4 implements a current-feedback architecture with internally trimmed 402Ω RF/RG networks, enabling precise fixed gains of +2, +1, or –1 without external resistors. Its output stage delivers high slew rate (≥1350 V/µs) and low crossover distortion while maintaining rail-to-rail-compatible headroom - critical for single-supply +5V operation with >200MHz bandwidth into 100Ω loads.
Each channel features independent disable control (DIS A/B/C), reducing supply current to <150µA/ch in shutdown while placing the output in high-impedance state. The SO-16 package supports signal flow-through PCB layout, and the device is characterized across –40°C to +85°C with guaranteed AC performance including 0.1dB gain flatness up to 120MHz (G = +2).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (G = +2) | 225 MHz min - ensures full NTSC/PAL video bandwidth with margin for cable loss and filter roll-off |
| Output Current | ±190 mA min - drives three 75Ω video lines simultaneously or sustains >120mA into 100Ω load on +5V supply |
| Supply Current (per ch) | 5.1 mA typ at +25°C - enables triple-channel video buffering with total quiescent draw <16 mA on ±5V |
| Disable Current (per ch) | 150 µA max - reduces system standby power by >97% vs active mode, supporting dynamic channel gating |
| Output Swing (no load) | ±4.0 V min - delivers 8VPP signal headroom on ±5V rails, or 1V–4V swing on +5V single supply |
| Input Voltage Noise | 1.7 nV/√Hz typ - preserves SNR in high-gain video chains where noise contribution must stay <0.1% of signal |
| Differential Gain/Phase | 0.07%/0.02° typ (NTSC, 150Ω) - meets broadcast-grade video fidelity requirements without external trimming |
Pinout & Package
OPA3692IDRG4 is packaged in SO-16 (D package), with lead finish RoHS-compliant and moisture sensitivity level MSL-2 per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9 (DIS A/B/C) | Channel disable control | Active-low logic input; pull LOW to place respective amplifier output in high-Z and reduce supply current to <150µA |
| 2, 6, 10 (+IN A/B/C) | Noninverting input | High-impedance (100kΩ || 2pF) input node; accepts DC- or AC-coupled video signals with 1.5V min headroom to rails |
| 3, 7, 11 (–IN A/B/C) | Inverting input | Internally connected to 402Ω feedback network; grounding selects G = +2; open-circuit enables G = +1 |
| 4, 12 (OUT A/C) | Amplifier output | Capable of sourcing/sinking ±190mA; optimized pinout minimizes parasitic inductance for >200MHz stability |
| 8, 16 (–VS) | Negative supply rail | Accepts –2.5V to –6V; tied to ground in single-supply +5V operation |
| 13, 15 (+VS) | Positive supply rail | Accepts +2.5V to +6V dual or +5V to +12V single; decoupling with 0.1µF + 6.8µF recommended |
| 14 (OUT B) | Amplifier output | Identical drive capability to OUT A/C; pin placement supports symmetric trace routing in RGB layouts |
Key Features
| Feature | Design Value |
|---|---|
| Internally fixed gain options | G = +2 (–IN grounded), G = +1 (–IN open), or G = –1 (–IN tied to feedback node) - eliminates external resistor matching errors and board space |
| Improved high-frequency pinout | Signal flow-through layout (input→output→supply) minimizes crosstalk and maintains impedance continuity for >200MHz video paths |
| Low disabled current | <150µA per channel in shutdown - enables dynamic power gating in multi-channel video systems without external FETs |
| Single-supply operation | 1V–4V output swing on +5V rail with >120mA drive - supports direct interface to 10-bit ADCs like ADS826 without level-shifting |
| Enhanced harmonic distortion | –69 dBc 2nd-harmonic (5MHz, 2VPP, 100Ω) - meets broadcast video dG/dP specs without post-filtering or calibration |
Applications
| RGB Video Line Drivers | ADC Buffers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA3682IDR | Lower bandwidth (190MHz G=+2), higher supply current (6.5mA/ch), no disable function | Lacks channel power gating; unsuitable for dynamic power management or battery-powered portable instruments | Select when disable control is unnecessary and cost is prioritized over bandwidth margin |
| OPA3691IDR | Dual-channel version; identical AC specs but only two amplifiers per package; same SO-8 footprint | Requires two packages for triple-channel use - increases board area and BOM count vs single OPA3692IDRG4 | Select when system uses only two video channels or needs footprint compatibility with existing dual-channel designs |
Compared with OPA3692IDRG4, OPA3682IDR trades 35MHz bandwidth and disable capability for lower unit cost, while OPA3691IDR offers identical per-channel performance in half the channel count - making OPA3692IDRG4 the only single-package solution delivering triple-channel, high-bandwidth, and power-gatable video buffering.

FAQ
What supply voltage ranges does the OPA3692IDRG4 support?
The OPA3692IDRG4 supports ±2.5V to ±6V dual supplies or +5V to +12V single supply operation. At ±5V, it delivers 225MHz bandwidth and ±4.0V output swing; on +5V, it achieves 1V–4V output with >120mA drive. Absolute maximum ratings cap at ±6.5V, and operation beyond ±6V or +12V risks permanent damage.
How does the OPA3692IDRG4 achieve fixed gain without external resistors?
The OPA3692IDRG4 integrates precision-trimmed 402Ω RF and RG resistors internally. Grounding the –IN pin configures G = +2; leaving –IN open yields G = +1; connecting –IN to the feedback node sets G = –1. This eliminates resistor matching errors, saves PCB area, and ensures gain accuracy within ±0.3% at +25°C.
What is the disable behavior of the OPA3692IDRG4, and how fast does it respond?
Driving DIS A/B/C LOW places the corresponding amplifier output in high-impedance state and reduces its supply current to <150µA/ch. Enable time is 25ns and disable time is 1µs (typ), with turn-on/off glitches limited to ±50mV and ±20mV respectively - enabling clean multiplexing between video channels during sync intervals.
Can the OPA3692IDRG4 drive 75Ω video cables directly?
Yes - the OPA3692IDRG4 delivers ±190mA output current and is characterized into 100Ω loads, exceeding the 40mA requirement for driving 75Ω coaxial cables (e.g., RG-59). Its 0.07% differential gain and 0.02° differential phase error at NTSC frequencies meet broadcast video standards without external equalization.
What package and thermal characteristics apply to the OPA3692IDRG4?
The OPA3692IDRG4 uses SO-16 (D package) with θJA = 100°C/W. It operates from –40°C to +85°C and has a maximum junction temperature of +175°C. The package supports flow-through PCB routing and is RoHS-compliant with MSL-2 moisture sensitivity - compatible with standard reflow profiles.
