Product details
Overview
OPA693IDBVT from Texas Instruments is a fixed-gain, ultra-wideband current-feedback video buffer amplifier in SOT-23-6 package, delivering 700MHz small-signal bandwidth (G = +2), 2500V/µs slew rate, and ±120mA output drive at ±5V supply - optimized for RGB line driving and single-supply ADC input buffering.
For engineers reviewing the OPA693IDBVT datasheet, OPA693IDBVT pinout, OPA693IDBVT application, or OPA693IDBVT equivalent, key selection criteria include its internally trimmed 13mA quiescent current, disable-controlled power-down (<170µA), 0.2dB gain flatness up to 400MHz, and validated performance on +5V single supply with 2.5VPP swing into 100Ω.
Technical Context
The OPA693IDBVT employs a low-gain-stable current-feedback architecture with internal 300Ω RF and RG resistors, enabling fixed gains of +2, +1, or –1 without external components. Its output stage delivers high current with minimal headroom - achieving ±3.8V swing into 100Ω at ±5V and >500MHz bandwidth on +5V single supply.
It integrates a dedicated DIS pin with TTL-compatible enable/disable thresholds (3.3V min enable, 1.8V max disable), 25ns enable time, and 3µs disable time. Output isolation exceeds 70dB at 5MHz in disabled state, and turn-on/off glitches are limited to ±100mV and ±20mV respectively under defined load conditions.
Key Specifications

Pinout & Package
SOT-23-6 package (DBV), 6-pin surface-mount, thermal resistance θJA = 150°C/W, operating ambient range –40°C to +85°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA695IDBVT | Higher 900MHz bandwidth, 3200V/µs slew rate, but 20mA IQ; no internal gain resistors - requires external RF/RG for fixed gain. | Better suited for >1080p120 or 4K2K baseband video; less ideal for cost-sensitive, space-constrained RGB line drivers. | Choose OPA695IDBVT when bandwidth headroom >200MHz is required and external resistor placement is acceptable. |
| LMH6702MF/NOPB | 720MHz bandwidth, 1000V/µs slew rate, 12.5mA IQ; unity-gain stable voltage-feedback architecture - higher noise (2.1nV/√Hz) and lower output current (±80mA). | Preferred for precision DC-coupled applications needing rail-to-rail input; not optimized for 75Ω cable driving or fast disable. | Choose LMH6702MF/NOPB when DC accuracy and low offset (<0.5mV) outweigh bandwidth and output drive requirements. |
Compared with OPA695IDBVT and LMH6702MF/NOPB, the OPA693IDBVT uniquely combines internal fixed-gain topology, sub-170µA disable current, and 700MHz bandwidth at 13mA - making it the most integrated solution for cost- and power-sensitive video line driving where external resistor count must be minimized.

FAQ
What is the maximum small-signal bandwidth of the OPA693IDBVT at G = +2?
The OPA693IDBVT achieves a minimum small-signal bandwidth of 700MHz at G = +2 with ±5V supplies, as specified in the Electrical Characteristics table (SBOS285A, page 3). This bandwidth is measured with VO < 1.0VPP into a 100Ω load and remains ≥480MHz over the full –40°C to +85°C temperature range - enabling reliable 1080p60 video signal transmission without external equalization.
Can the OPA693IDBVT operate from a single +5V supply?
Yes, the OPA693IDBVT supports single-supply operation from +5V to +12V. At +5V, it delivers >500MHz bandwidth with 2.5VPP output swing into a 100Ω load referenced to VS/2 (2.5V), and maintains ±3.8V output voltage swing capability. The input common-mode range extends from 1.6V to 3.4V, allowing direct AC-coupling of video signals with simple resistive biasing - confirmed in Figure 4 and Electrical Characteristics (page 5).
How does the disable (DIS) pin function on the OPA693IDBVT?
The DIS pin on the OPA693IDBVT provides TTL-compatible power-down control: pulling DIS LOW disables the amplifier, reducing supply current to <170µA and placing the output in high-impedance state with >70dB off-isolation at 5MHz. Leaving DIS open or HIGH enables normal operation. Enable time is 25ns and disable time is 3µs, with turn-on/off glitches limited to ±100mV and ±20mV respectively - making it suitable for dynamic video channel switching.
What are the internal gain-setting resistors in the OPA693IDBVT?
The OPA693IDBVT integrates internal 300Ω RF and RG resistors, enabling fixed gains of +2 (–IN grounded), +1 (RG open), or –1 (RG connected externally to match source impedance) without external components. These resistors are trimmed to ±10% tolerance (300Ω ±30Ω) and exhibit <0.03%/°C average drift - ensuring stable gain accuracy across temperature without calibration overhead.
Is the OPA693IDBVT suitable for driving 75Ω coaxial video cables?
Yes, the OPA693IDBVT is explicitly characterized for 75Ω video applications: differential gain/phase are 0.03%/0.01° (NTSC, 150Ω load) and harmonic distortion is –69dBc (2nd) / –83dBc (3rd) at 10MHz into 100Ω - both meeting or exceeding SMPTE 253M broadcast standards. Its ±120mA output drive and low 0.18Ω closed-loop output impedance ensure minimal signal reflection and amplitude loss on 75Ω lines.
