Product details
Overview
OPA683IDBVR from Texas Instruments is a very low-power, current-feedback operational amplifier with disable control, designed for high-speed analog signal conditioning in space- and power-constrained systems. It delivers 150MHz bandwidth at G = +2, 110mA output drive, < –69dBc harmonic distortion at 5MHz, and operates from single +5V to +12V or dual ±2.5V to ±6V supplies - enabling use in broadcast video drivers and ADC input stages.
For engineers reviewing the OPA683IDBVR datasheet, OPA683IDBVR pinout, OPA683IDBVR application, or OPA683IDBVR equivalent, key selection criteria include its CFBplus architecture for gain-stable bandwidth, 0.94mA quiescent current, 40ns enable time, 100µA shutdown current, and SOT-23-6 package compatibility with high-density PCB layouts.
Technical Context
The OPA683IDBVR implements a patented CFBplus architecture featuring an internally closed-loop input buffer stage that linearizes inverting-input impedance, enabling exceptional bandwidth retention up to G = +100 and reduced harmonic distortion versus conventional low-power CFB amplifiers. Its transimpedance gain (ZOL) exceeds 700kΩ at 25°C, supporting stable closed-loop operation with minimal gain-dependent peaking.
It supports both inverting and noninverting configurations with RF = 1.2kΩ (dual supply) or 1.4kΩ (single +5V), and includes a dedicated DIS pin that places I/O in high-impedance state while reducing supply current to ≤100µA. Input common-mode range extends to ±3.6V on ±5V supplies, and output swing reaches ±4.0V into 1kΩ.

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the maximum small-signal bandwidth of the OPA683IDBVR at G = +2?
The OPA683IDBVR achieves a typical small-signal bandwidth of 150MHz at G = +2 with RF = 1.2kΩ and ±5V supplies. This is validated across –40°C to +85°C, with minimum guaranteed bandwidth of 117MHz at +85°C. Bandwidth remains >90MHz even at G = +10, demonstrating the CFBplus architecture's gain-stability advantage over conventional low-power amplifiers.
Does the OPA683IDBVR support single-supply operation, and what is its minimum operating voltage?
Yes, the OPA683IDBVR supports true single-supply operation down to +2.8V. At +5V supply, it delivers 119MHz bandwidth (G = +2), ±4.0V output swing into 1kΩ, and 0.82mA quiescent current. The input common-mode range extends from 1.1V to 3.9V, and output swings from 0.8V to 4.2V - enabling rail-to-rail signal handling in +5V systems without level-shifting circuitry.
How does the disable function of the OPA683IDBVR behave during power-down?
When the DIS pin of the OPA683IDBVR is pulled LOW (<1.5V), the amplifier enters low-power state with supply current dropping to ≤100µA, output and inputs entering high-impedance state, and off-isolation exceeding 70dB at 5MHz. Enable time is 40ns, turn-on glitch is ±70mV, and output capacitance in disable is only 1.7pF - ensuring clean, fast switching in time-multiplexed signal paths without crosstalk.
What are the thermal limitations of the OPA683IDBVR in SOT-23-6 package?
The OPA683IDBVR in SOT-23-6 (DBV) package has a junction-to-ambient thermal resistance (θJA) of 150°C/W. With 0.94mA quiescent current at ±5V (4.7mW dissipation), junction temperature rise is ~0.7°C above ambient under no-load conditions. Under full 150mA output drive into 100Ω, power dissipation can reach ~200mW, raising junction temperature by up to 30°C - well within the +175°C absolute maximum rating.
Can the OPA683IDBVR drive a 75Ω video load while maintaining broadcast video specifications?
Yes, the OPA683IDBVR drives 75Ω loads with ±4VPP swing and meets broadcast video linearity specs: 0.06% differential gain and 0.03° differential phase (NTSC). Its 150mA sourcing capability ensures stable 75Ω termination, and <–69dBc harmonic distortion at 5MHz prevents color bleeding and luminance artifacts - satisfying SMPTE 259M and ITU-R BT.601 requirements.
