Product details
Overview
OPA3693IDBQRG4 from Texas Instruments is a triple, ultra-wideband, fixed-gain video buffer amplifier with disable control, delivering 650MHz small-signal bandwidth at G = +2, ±4.1V output swing into no load, and 2500V/µs slew rate under ±5V supply. It operates as an RGB line driver or ADC input buffer in high-fidelity analog video distribution systems.
For engineers reviewing the OPA3693IDBQRG4 datasheet, OPA3693IDBQRG4 pinout, OPA3693IDBQRG4 application, or OPA3693IDBQRG4 equivalent, key selection criteria include gain configuration flexibility (±1 or +2), low 130mW/channel quiescent power, sub-25ns enable/disable timing, and SSOP-16 package compatibility with high-density video routing layouts.
Technical Context
The OPA3693IDBQRG4 employs a current-feedback architecture with internal 300Ω RF and RG resistors, enabling stable fixed-gain operation without external feedback components. Its output stage delivers high current (±100mA) with minimal headroom-±3.8V into 100Ω-supporting DC-coupled video signal paths.
Each of its three independent channels features a dedicated disable pin (DIS A/B/C), allowing per-channel power gating with <1µs disable time and 25ns enable time. The device supports both dual-supply (±5V) and single-supply (+5V) operation, with input common-mode range extending to ±VS and output swing within 1.2V of either rail.

| 11 (+VS) | Positive supply rail (redundant) | Dual power pin improves current delivery and reduces supply impedance for high-frequency transients |
| 12 (–VS) | Negative supply rail (redundant) | Second ground return path enhances PSRR and reduces crosstalk between channels |
| 13 (DIS A) | Disable control, Channel A | Enables per-channel power gating; critical for battery-powered video encoders with variable channel usage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA3695IDBQR | Higher 900MHz bandwidth but no internal RG/RF; requires external resistors for gain setting | Better suited for >1080p60 or 4K2K pre-distortion compensation where bandwidth >800MHz is mandatory | Select OPA3695IDBQR only when absolute maximum bandwidth is required and board space allows external resistor placement |
| LMH6738MA/NOPB | Triple-channel, 650MHz, but uses voltage-feedback topology; higher 2.1nV/√Hz noise and 1500V/µs slew rate | Preferred in cost-sensitive industrial video where lower power consumption (85mW/ch) outweighs speed requirements | Choose LMH6738MA/NOPB for applications prioritizing power efficiency over transient fidelity in 720p systems |
Compared with OPA3695IDBQR and LMH6738MA/NOPB, the OPA3693IDBQRG4 uniquely combines internal gain-setting resistors, lowest noise (1.8nV/√Hz), and fastest slew rate (2500V/µs) in a single ±5V-compatible triple video buffer-making it optimal for broadcast-grade RGB distribution where layout simplicity and signal purity are critical.

FAQ
What gain configurations does the OPA3693IDBQRG4 support?
The OPA3693IDBQRG4 supports fixed gains of +2, +1, and –1 per channel using its internal 300Ω RF and RG resistor network. For G = +2, connect –IN to ground; for G = +1, leave RG open; for G = –1, terminate –IN with 300Ω to ground. All configurations require no external resistors, eliminating gain drift and parasitic effects in high-frequency video paths. The OPA3693IDBQRG4 datasheet specifies performance across all three modes, including bandwidth, distortion, and settling time.
Can the OPA3693IDBQRG4 operate from a single +5V supply?
Yes, the OPA3693IDBQRG4 supports true single +5V operation with input common-mode range from 1.6V to 3.4V and output swing from 0.8V to 4.2V (no load). It delivers 500MHz small-signal bandwidth and 1500V/µs slew rate under +5V, making it suitable for portable video equipment. The OPA3693IDBQRG4 maintains specified harmonic distortion (–62dBc) and gain flatness (280MHz @ 0.2dB) in this configuration, as verified in the +5V Electrical Characteristics table.
How does the disable function work on the OPA3693IDBQRG4?
The OPA3693IDBQRG4 features three independent active-low disable pins (DIS A/B/C, Pins 13/5/6) that reduce channel supply current to <665µA while maintaining >70dB off-isolation at 10MHz. Pulling DIS low disables the output stage and places it in high-impedance state, with 4pF output capacitance minimizing feedthrough. Enable time is 25ns and disable time is 1µs, enabling rapid channel switching in broadcast infrastructure. The OPA3693IDBQRG4 retains full specification compliance across temperature when disabled.
What is the thermal performance of the OPA3693IDBQRG4 in SSOP-16 package?
The OPA3693IDBQRG4 in DBQ (SSOP-16) package has a junction-to-ambient thermal resistance (θJA) of 80°C/W, measured per JEDEC JESD51-7. At maximum quiescent current (43.5mA) and ±5V supply, total power dissipation is ~435mW, resulting in ~35°C junction rise above ambient. The exposed thermal pad must be soldered to a minimum 100mm² copper pour for optimal heat transfer. The OPA3693IDBQRG4 is rated for continuous operation up to +140°C junction temperature, with derating applied above +85°C ambient.
Does the OPA3693IDBQRG4 require external compensation for 75Ω video loads?
No, the OPA3693IDBQRG4 is internally compensated for direct 75Ω load driving without external components. Its closed-loop output impedance is 0.18Ω at 100kHz, and stability is maintained with capacitive loads up to 100pF when RS = 10Ω is used in series with the output. The OPA3693IDBQRG4 datasheet Figure 16 provides recommended RS values versus capacitive load, confirming robust performance into standard RG-59 coaxial cable (≈50–70pF/m). No trim capacitor is needed for standard video distribution.
