OPA3693IDBQR

Video Amps And Modules Overview

The OPA3693IDBQR is a triple ultra-wideband fixed-gain video buffer amplifier manufactured by Texas Instruments. It integrates three independent channels within a single 16-pin SSOP package, designed for high-speed signal processing in video applications. The device operates on a single supply voltage ranging from 5 V to 12 V, with a typical operating current of 15.3 mA per channel. Key electrical specifications include a 3 dB bandwidth of 280 MHz and a power supply rejection ratio (PSRR) of 62 dB typical. Input characteristics feature an input bias current of 40 µA and an input offset voltage of 3.5 mV. The component supports fixed voltage gains of 1 V/V and 2 V/V, ensuring precise signal buffering without external gain-setting resistors.

Video Amps And Modules Feature Summary

• Triple-channel architecture providing three independent ultra-wideband video buffers in a compact package
• Fixed-gain configuration eliminating the need for external feedback components for standard gain settings
• Integrated disable function allowing individual channel control to reduce power consumption during idle states

Video Amps And Modules Applications

• High-speed video signal distribution and buffering
• Professional video equipment requiring multi-channel signal integrity
• Video multiplexer input stages

Video Amps And Modules Procurement Notes

Verify the specific suffix 'RG4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the SSOP-16 package type matches your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your system's environmental conditions. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Video Amps And Modules Selection Notes

Select this component when multiple high-bandwidth video signals require simultaneous buffering with minimal external component count. The fixed-gain options simplify circuit design compared to variable-gain amplifiers. Consider the 280 MHz bandwidth limit for signal frequency requirements. Evaluate the 15.3 mA quiescent current against total system power budgets. The disable feature offers flexibility for power management in portable or battery-operated video devices.

Video Amps And Modules Part Context

The OPA3693 belongs to Texas Instruments' family of ultra-wideband video amplifiers, distinct from the OPA3691 (current-feedback op amp) and OPA3692 (dual wideband buffer). Unlike general-purpose operational amplifiers, this device is optimized specifically for video signal integrity with fixed gain structures. It shares the triple-channel topology with other members like the OPA3695 but differs in internal architecture and gain configuration.
