OPA3692IDBQT

Video Amps And Modules Overview

The OPA3692IDBQT is a triple, wideband, fixed-gain video buffer amplifier manufactured by Texas Instruments. It features an internal fixed gain of +2 V/V or ±1 V/V, selectable via external connections. The device operates on a single supply voltage ranging from +5 V to +12 V or dual supplies of ±2.5 V to ±6 V. Key electrical parameters include a 3 dB bandwidth of 280 MHz at a gain of +2, a maximum input offset voltage of 3.5 mV, and an input bias current of 40 µA. It draws 15.3 mA of operating power supply current and supports a maximum output current of 190 mA. The unit is housed in a 16-lead SSOP package and functions within a temperature range of -40°C to +85°C.

Video Amps And Modules Feature Summary

• Integrates three wideband video buffer amplifiers with selectable fixed gains of +2 or ±1 V/V via internal resistor networks.
• Includes a dedicated disable control pin that significantly reduces power consumption when the device is not in active use.
• Supports flexible power supply configurations for both single-supply (+5 V to +12 V) and dual-supply (±2.5 V to ±6 V) operation.

Video Amps And Modules Applications

• RGB video line drivers
• Video multiplexing circuits
• Buffering signals for multi-channel video analog-to-digital converters

Video Amps And Modules Procurement Notes

Verify the specific suffix 'QT' against the manufacturer's official documentation to confirm it denotes the tape and reel packaging variant rather than a different functional specification. Ensure the selected component matches the required 16-lead SSOP form factor and meets the specified industrial temperature range limits for the target application environment.

Video Amps And Modules Selection Notes

Select this component when high-speed signal buffering with fixed gain is required without the need for external feedback resistors. It is suitable for designs needing low quiescent current per channel and the ability to enter a low-power state via the disable pin. Consider the 280 MHz bandwidth and 190 mA output drive capability when driving capacitive loads or long transmission lines.

Video Amps And Modules Part Context

This part belongs to the OPA3692 series of wideband video amplifiers. It serves as a direct replacement for older models like the OPA3682, offering improved performance characteristics while maintaining similar functionality. The series is designed specifically for video applications requiring precise gain settings and fast transient response.

Video Amps And Modules Replacement Considerations

The OPA3692IDR is a documented alternative within the same family, differing primarily in the SOIC-16 package instead of the SSOP-16 used by the IDBQT variant. Verify pinout compatibility and thermal dissipation requirements before substituting packages.
