Product details
Overview
OPA3692IDBQR from Texas Instruments is a triple, wideband, fixed-gain video buffer amplifier with disable control, designed for RGB line driving and ADC input 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.
For engineers reviewing the OPA3692IDBQR datasheet, OPA3692IDBQR pinout, OPA3692IDBQR application, or OPA3692IDBQR equivalent, this page provides verified specifications, SSOP-16 package details, RGB/ADC/video filter use cases, and validated alternative parts for high-speed analog signal conditioning in video and instrumentation systems.
Technical Context
The OPA3692IDBQR uses a current-feedback architecture with internally trimmed 402Ω RF/RG resistors enabling precise G=+2, +1, or –1 gain configurations without external components. Its improved high-frequency pinout minimizes parasitic coupling and supports clean signal flow-through PCB layout.
Each channel features independent disable control (DIS A/B/C), reducing supply current to <150µA/ch while placing the output in high-impedance state. The output stage delivers >160mA into 100Ω loads with minimal crossover distortion and <1.9ns rise/fall time at G=+2, enabling robust single-supply operation down to +5V.

FAQ
What supply voltages does the OPA3692IDBQR support?
The OPA3692IDBQR supports ±2.5V to ±6V dual supplies or +5V to +12V single supply operation. At +5V single supply, it delivers 3Vp-p output swing with >150MHz bandwidth and maintains specified AC performance across the full –40°C to +85°C temperature range. The device's supply voltage independent biasing ensures stable quiescent current and gain accuracy regardless of rail choice.
How is gain configured on the OPA3692IDBQR?
Gain on the OPA3692IDBQR is set via internal 402Ω RF/RG resistors and external pin connections: G=+2 requires grounding the –IN pin; G=+1 leaves –IN open; G=–1 connects –IN to the output. No external resistors are needed. All configurations are validated in the datasheet with ≤±0.3% gain error at G=+2 and <0.13%/°C drift, ensuring predictable performance without trimming.
What is the disable behavior of the OPA3692IDBQR?
When the DIS pin for any channel is pulled LOW, that channel's supply current drops to <150µA and its output enters high-impedance state. Enable/disable times are 25ns and 1µs respectively, with turn-on/off glitches limited to ±50mV and ±20mV. This allows safe multiplexing between video sources during retrace intervals without signal contention or loading effects on active channels.
Does the OPA3692IDBQR require external compensation for video loads?
No-OPA3692IDBQR is internally compensated for stable operation into 75Ω or 100Ω video loads. Its improved high-frequency pinout and optimized output stage eliminate need for external series resistors in most configurations. For capacitive loads >100pF, a small series resistor (e.g., 3–9Ω) at the output is recommended per Figure 7 in the datasheet to maintain phase margin and prevent peaking.
What is the thermal performance of the OPA3692IDBQR in SSOP-16 package?
The OPA3692IDBQR in SSOP-16 (DBQ) package has a junction-to-ambient thermal resistance (θJA) of 100°C/W. At maximum rated dissipation (17.4mA × 5V = 87mW per channel), junction temperature rise is ≤8.7°C above ambient-well within the +175°C absolute max rating. Derating is required only above +85°C ambient per TI's thermal guidelines in SBOS228E.
