Product details
Overview
OPA3692IDR from Texas Instruments is a triple, wideband, fixed-gain video buffer amplifier with disable control, designed for RGB line driving and ADC buffering. It delivers 225MHz bandwidth at G = +2, ±4.0V output swing, 190mA output current, and operates on ±5V dual or +5V to +12V single supply - enabling high-fidelity analog video signal conditioning in compact portable instrumentation and broadcast-grade systems.
For engineers reviewing the OPA3692IDR datasheet, OPA3692IDR pinout, OPA3692IDR application, or OPA3692IDR equivalent, key selection criteria include its internally trimmed 5.1mA/ch quiescent current, 150µA/ch power-down mode, 2000 V/µs slew rate (G = +2), 0.02% settling in 12ns, and differential gain/phase error of 0.07%/0.02° (NTSC, RL = 150Ω).
Technical Context
The OPA3692IDR uses a current-feedback architecture with internal 402Ω RF/RG resistor networks, enabling precise fixed gains of +2, +1, or –1 without external components. Its output stage delivers high current with minimal headroom and crossover distortion, supporting rail-swinging operation down to 1V from either supply rail.
It features three independent disable pins (DIS A/B/C), each controlling one amplifier channel: pulling DIS LOW places the output in high-impedance state while reducing supply current to <150µA/ch. The pinout is optimized for high-frequency signal integrity, with matched input/output paths and minimized parasitic coupling between channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA3682IDR | Lower bandwidth (190 MHz G = +2), higher quiescent current (6.5 mA/ch), no disable function | Lacks per-channel power-down; unsuitable for battery-powered or multiplexed systems requiring dynamic channel gating | Select OPA3682IDR only if disable control is unnecessary and cost is prioritized over bandwidth/power |
| OPA3691IDR | Dual-channel version; identical AC specs but only two amplifiers per package; same disable functionality | Requires two packages for triple-channel use, increasing board area and BOM count | Choose OPA3691IDR only when design already uses dual-channel topology or needs staggered channel enable timing |
Compared with OPA3682IDR and OPA3691IDR, the OPA3692IDR uniquely delivers triple-channel integration, 225 MHz bandwidth, and per-channel disable in a single SO-16 package - reducing PCB footprint by 33% versus dual + single solutions and enabling >97% per-channel power reduction during idle intervals.

FAQ
What supply voltages does the OPA3692IDR support?
The OPA3692IDR supports ±2.5V to ±6V dual supplies or +5V to +12V single supply operation. At ±5V, it delivers 225 MHz bandwidth and ±4.0V output swing; on +5V, it achieves >200 MHz bandwidth with 3Vp-p output swing and 1V headroom from each rail. Absolute maximum ratings limit supply to ±6.5VDC.
How does the OPA3692IDR achieve low crossover distortion in its output stage?
The OPA3692IDR uses a proprietary output stage architecture that delivers high bipolar output current with minimal headroom and reduced crossover distortion. This enables exceptional linearity - evidenced by –76 dBc 3rd-harmonic distortion at 5 MHz - even when sourcing/sinking >160 mA into 100Ω loads on single +5V supply, unlike conventional current-feedback amplifiers.
Can the OPA3692IDR be used in a single-supply configuration with AC-coupled inputs?
Yes - the OPA3692IDR is explicitly characterized for single +5V operation with AC-coupled inputs. Figure 2 in the datasheet shows a bias network using two 806Ω resistors to establish 2.5V midpoint, allowing ±1.5V input swing. With this configuration, it delivers >150 MHz bandwidth and 3Vp-p output swing while maintaining <0.17% differential gain error on NTSC signals.
What is the purpose of the three separate DIS pins on the OPA3692IDR?
The OPA3692IDR provides independent DIS A, DIS B, and DIS C pins (Pins 9, 3, and 6) to enable per-channel power-down. Pulling any DIS pin LOW disables its corresponding amplifier, reducing its supply current to <150 µA/ch and placing its output in high-impedance state - essential for power-gated multiplexed ADC drivers or dynamic RGB channel blanking in video systems.
Does the OPA3692IDR require external gain-setting resistors?
No - the OPA3692IDR integrates precision 402Ω RF and RG resistors, enabling fixed gains of +2 (–IN grounded), +1 (–IN open), or –1 (–IN connected to OUT) without external components. This simplifies PCB layout, improves gain accuracy (±0.3% max at G = +2), and eliminates resistor-induced thermal drift and noise in high-frequency video paths.
