Product details
Overview
OPA3692IDBQRG4 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.
For engineers reviewing the OPA3692IDBQRG4 datasheet, OPA3692IDBQRG4 pinout, OPA3692IDBQRG4 application, or OPA3692IDBQRG4 equivalent, key selection criteria include gain configuration (+2/+1/–1), disable timing (25ns enable / 1µs disable), high-frequency crosstalk performance (–82dBc at 5MHz), and SSOP-16 package compatibility with video signal routing constraints.
Technical Context
The OPA3692IDBQRG4 uses a current-feedback architecture with internally trimmed 402Ω RF/RG resistors to support fixed gains of +2, +1, or –1 without external components. Its output stage delivers high slew rate (1350 V/µs min) and low crossover distortion while maintaining <1V headroom from rails.
Each channel features independent disable control (DIS A/B/C), enabling dynamic power management in multiplexed systems. The SSOP-16 package implements an improved high-frequency pinout with interleaved inputs/outputs and dedicated ±VS pins per pair to minimize crosstalk and ground bounce in RGB and differential receiver applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth (G = +2) | 225 MHz min - supports NTSC/PAL and HD component video signal integrity up to 1080i. |
| Output Current (Sourcing/Sinking) | ±190 mA min - drives three 75Ω video lines simultaneously with <0.1% gain error. |
| Supply Current per Channel | 5.1 mA typ at +25°C - enables triple-channel operation at ≤15.3 mA total quiescent current on ±5V. |
| Disable Current per Channel | 150 µA max - reduces total supply current to <450 µA when all channels disabled. |
| Output Voltage Swing | ±3.9 V min into 100Ω - delivers 7.8 VPP full-scale video swing on ±5V supplies with headroom margin. |
| Differential Gain/Phase Error | 0.07% / 0.02° typ (NTSC, 150Ω) - meets broadcast-grade video fidelity requirements. |
| Channel Crosstalk | –82 dBc typ at 5MHz - ensures isolated RGB channel operation without color bleeding. |
Pinout & Package
OPA3692IDBQRG4 is packaged in a 16-pin SSOP (DBQ) with 0.64 mm pitch, optimized for high-frequency layout: dual ±VS pins (pins 10 & 14), interleaved input/output pairs, and dedicated DIS pins per channel to minimize switching noise coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (–IN A) | Inverting input, Channel A | Grounded for G = +2; open for G = +1; connected to feedback for G = –1. |
| 2 (+IN A) | Noninverting input, Channel A | Main signal input node; 100 kΩ || 2 pF impedance minimizes loading on source. |
| 3 (DIS B) | Disable control, Channel B | Pulled LOW disables Channel B output (high-Z); open or HIGH enables normal operation. |
| 4 (–IN B) | Inverting input, Channel B | Same configuration flexibility as Pin 1 for independent gain setting per channel. |
| 5 (+IN B) | Noninverting input, Channel B | Signal input for second video/ADC channel; matched layout to Pin 2 for skew control. |
| 6 (DIS C) | Disable control, Channel C | Independent enable/disable for third channel; supports time-multiplexed video routing. |
| 7 (–IN C) | Inverting input, Channel C | Configurable gain node identical to Pins 1 and 4; internal 402Ω resistor network referenced. |
| 8 (+IN C) | Noninverting input, Channel C | Third signal path input; pinout symmetry enables balanced PCB trace routing. |
| 9 (DIS A) | Disable control, Channel A | First-channel disable; placed adjacent to +IN A/–IN A to reduce parasitic coupling. |
| 10 (+VS) | Positive supply, shared | Dual +VS pins (10 & 14) lower supply inductance for high-frequency transient response. |
| 11 (OUT A) | Output, Channel A | Capable of ±190 mA drive; low 0.12 Ω closed-loop output impedance at 100 kHz. |
| 12 (–VS) | Negative supply, shared | Dual –VS pins (12 & 16) provide low-inductance return path for all three outputs. |
| 13 (OUT B) | Output, Channel B | Matched drive strength and settling (8 ns to 0.1%) as OUT A for synchronized RGB timing. |
| 14 (+VS) | Positive supply, shared | Second +VS connection improves PSRR (58 dB min) and reduces supply-induced crosstalk. |
| 15 (OUT C) | Output, Channel C | Full 225 MHz bandwidth delivery with <2.3 ns rise/fall time for high-resolution video edges. |
| 16 (–VS) | Negative supply, shared | Second –VS pin completes low-impedance supply loop; critical for harmonic distortion <–76 dBc. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA3682IDBQR | Lower bandwidth (190 MHz G=+2), higher supply current (6.5 mA/ch), no disable function. | Lacks dynamic power control; unsuitable for time-multiplexed or battery-powered video systems. | Select OPA3682IDBQR only if disable functionality and sub-1µA shutdown current are not required. |
| OPA3691IDBVR | Current-feedback dual op amp (not triple); 250 MHz bandwidth but no integrated disable pins. | Requires two devices and external logic for triple-channel operation; increases layout complexity and BOM count. | Choose OPA3691IDBVR only when higher bandwidth (>225 MHz) is mandatory and channel count can be met with duals + duplication. |
Compared with OPA3682IDBQR and OPA3691IDBVR, the OPA3692IDBQRG4 uniquely integrates triple-channel operation, per-channel disable, and 225 MHz bandwidth in a single SSOP-16 package-reducing PCB area by 30% and eliminating inter-device skew in RGB timing-critical systems.

FAQ
What gain configurations does the OPA3692IDBQRG4 support, and how are they set?
The OPA3692IDBQRG4 supports fixed gains of +2, +1, and –1 via pin-strapping. For G = +2, ground the –IN pin and drive +IN; for G = +1, leave –IN open and drive +IN; for G = –1, connect –IN to the output and drive +IN. Internal 402Ω resistors eliminate external components, ensuring ±0.3% gain accuracy over temperature. All configurations are validated in the OPA3692IDBQRG4 datasheet under Electrical Characteristics.
How does the disable function operate on the OPA3692IDBQRG4, and what is its timing behavior?
The OPA3692IDBQRG4 features independent DIS pins (DIS A/B/C) per channel. Pulling a DIS pin LOW disables that channel, reducing supply current to <150 µA/ch and placing the output in high-impedance state. Enable time is 25 ns and disable time is 1 µs (measured at VIN = +1VDC). Glitch energy is limited to ±50 mV turn-on and ±20 mV turn-off, making it safe for multiplexed video switching during sync intervals. This behavior is characterized in the OPA3692IDBQRG4 Electrical Characteristics table.
Can the OPA3692IDBQRG4 operate from a single +5V supply, and what output swing is achievable?
Yes, the OPA3692IDBQRG4 operates from a single +5V supply (specified range: +5V to +12V). With proper AC-coupling and biasing (e.g., 2.5V midpoint), it delivers a 3 VPP output swing with >150 MHz bandwidth and >120 mA drive current. Under load, minimum output swing is +3.9 V / +1.1 V (7.8 VPP total) into 100Ω, as confirmed in the +5V Electrical Characteristics section of the OPA3692IDBQRG4 datasheet.
What is the maximum small-signal bandwidth of the OPA3692IDBQRG4 at G = +2, and how is it measured?
The OPA3692IDBQRG4 achieves a minimum small-signal bandwidth of 225 MHz at G = +2 with VO < 0.5 VPP, tested under ±5V supplies and 100Ω load per the standard test circuit in Figure 1 of the OPA3692IDBQRG4 datasheet. This value is guaranteed across –40°C to +85°C and represents the –3dB point where gain drops 3 dB from midband. Typical performance reaches 280 MHz, supporting high-definition video formats including 1080p60.
How does the OPA3692IDBQRG4 compare to the OPA3682 in terms of video performance and power efficiency?
The OPA3692IDBQRG4 improves upon the OPA3682 with 225 MHz vs. 190 MHz bandwidth (G = +2), 5.1 mA vs. 6.5 mA supply current per channel, and integrated disable functionality (150 µA/ch vs. no disable). It also offers superior differential gain/phase (0.07%/0.02° vs. 0.1%/0.05°) and lower crosstalk (–82 dBc vs. –75 dBc). These enhancements make the OPA3692IDBQRG4 the preferred upgrade for next-generation RGB line drivers requiring higher fidelity and dynamic power control.
