Product details
Overview
OPA692IDBVTG4 from Texas Instruments is a wideband, fixed-gain video buffer amplifier in SOT-23-6 package, delivering 190MHz bandwidth at G = +2 with ±5V supplies or 140MHz on +5V single supply, 5.1mA quiescent current, 160mA output drive, and integrated disable control-designed for RGB line driving and single-supply ADC input buffering.
For engineers reviewing the OPA692IDBVTG4 datasheet, OPA692IDBVTG4 pinout, OPA692IDBVTG4 application, or OPA692IDBVTG4 equivalent, key selection criteria include gain configuration flexibility (+2/+1/–1), low-power high-speed operation, disable-induced high-impedance I/O, and verified performance in video multiplexing and ADC interface circuits.
Technical Context
The OPA692IDBVTG4 employs a current-feedback architecture with internal 402Ω RF/RG resistors, enabling stable fixed-gain configurations without external components. Its output stage delivers high current (±160mA min on +5V) with minimal headroom (1.0V to 4.0V swing) and low crossover distortion.
It supports dual-supply (±2.5V to ±6V) and single-supply (5V to 12V) operation, with disable functionality reducing supply current to <150µA and placing I/O pins in high-impedance state. Gain flatness (120MHz @ 0.1dB) and harmonic distortion (–66dBc 2nd-harmonic @ 5MHz) are specified under 100Ω load conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar video buffer amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA691IDBVT | Current-feedback architecture, 250MHz bandwidth (G = +2), higher 7.5mA supply current, no disable pin | Lacks power-down mode; unsuitable for multiplexed or battery-powered systems requiring standby current <200µA | Select when maximum bandwidth is critical and disable functionality is unnecessary |
| OPA682IDBVR | Fixed-gain +2 video buffer, 180MHz bandwidth, 4.8mA supply current, disable pin included, but lower output current (±100mA) | Lower drive capability limits use with >75Ω loads or multi-line fanout; better for low-power portable video | Select when 100mA output suffices and quiescent current reduction below 5mA is prioritized |
Compared with OPA692IDBVTG4, OPA691IDBVT offers higher bandwidth but no disable function, while OPA682IDBVR provides lower power consumption at the cost of reduced output drive-making OPA692IDBVTG4 the optimal balance for high-fidelity, power-gated video and ADC interface designs.

FAQ
What gain configurations does the OPA692IDBVTG4 support, and how are they implemented?
The OPA692IDBVTG4 supports fixed gains of +2, +1, and –1 using its internal 402Ω RF and RG resistors. For G = +2, the inverting input is grounded; for G = +1 or –1, external connections configure the feedback network. No external resistors are needed for standard configurations, simplifying layout and improving stability. This is confirmed in the Applications Information section of the SBOS236E datasheet.
Can the OPA692IDBVTG4 operate from a single +5V supply, and what output swing is achievable?
Yes, the OPA692IDBVTG4 operates from a single +5V supply with a guaranteed output swing of 1.0V to 4.0V (min, no load) and 1.1V to 3.9V (min, 100Ω load). It delivers >140MHz bandwidth and >120mA drive current under these conditions, making it suitable for driving ADC inputs and 75Ω video loads without negative rail. These values are specified in the "ELECTRICAL CHARACTERISTICS: VS = +5V" table.
How does the disable (DIS) pin function, and what is its logic threshold?
The DIS pin disables the OPA692IDBVTG4 when pulled LOW (<1.5V max), reducing supply current to <150µA and placing I/O pins in high-impedance state. Normal operation occurs when DIS is left open or held HIGH (>3.3V min). Enable time is 25ns; disable time is 1µs. These thresholds and timing values are tested per the "DISABLE/POWER DOWN" section of the datasheet.
What is the harmonic distortion performance of the OPA692IDBVTG4 at 5MHz?
At 5MHz, 2VPP, and 100Ω load, the OPA692IDBVTG4 achieves –66dBc 2nd-harmonic and –72dBc 3rd-harmonic distortion on ±5V supplies. On +5V supply, it delivers –66dBc 2nd-harmonic and –72dBc 3rd-harmonic under identical conditions. These values are measured and specified in the "ELECTRICAL CHARACTERISTICS" tables for both supply configurations.
Is the OPA692IDBVTG4 suitable for driving multiple 75Ω video loads simultaneously?
Yes-the OPA692IDBVTG4 delivers ±160mA minimum output current on +5V supply into 100Ω, exceeding the 107mA required to drive three parallel 75Ω loads (3 × 75Ω = 25Ω equivalent). Its low output impedance (0.12Ω typ) and high slew rate (550V/µs min) ensure stable, low-glitch performance in RGB line driver applications, as validated in TI's video multiplexing reference design.
