What are the key features of OPA 693ID?
- Ultra-wideband fixed-gain video buffer with over 700 MHz -3 dB bandwidth for driving cables, ADC inputs, and video distribution lines with minimal signal degradation
- Hardware disable pin reduces quiescent current to under 1 mA, enabling power-efficient multi-channel video multiplexing without external switches
- Current-feedback amplifier architecture with SOIC-8 package supports ±5 V dual-supply operation for direct interface with standard 75 Ω video systems
What is OPA 693ID used for?
The OPA693ID is designed for ultra-wideband video signal distribution, cable driving, and ADC input buffering in broadcast and surveillance video equipment requiring flat frequency response beyond 700 MHz. Its fixed-gain configuration simplifies PCB design in multi-channel video routing switches and line drivers where consistent gain across channels is mandatory. The disable function makes it suitable for power-saving video multiplexers where unused channels are shut down to reduce total system power dissipation.

Frequently Asked Questions
What bandwidth does the OPA693ID deliver when driving a 75 Ω video cable from a ±5 V supply?
The OPA693ID achieves a -3 dB bandwidth exceeding 700 MHz when loaded with a 75 Ω back-termination into a 75 Ω cable, making it suitable for HD-SDI and wideband composite video signal distribution. At ±5 V supply, it delivers low output impedance across that bandwidth, preserving video signal integrity on cable runs without additional buffering stages or equalization.
How does the disable pin on the OPA693ID reduce power in a multi-channel video routing design?
Asserting the disable pin on the OPA693ID reduces the device's quiescent supply current from its active level to under 1 mA, effectively powering down an unused channel without switching supply rails. In an 8-channel video router where only 2 channels are active at a given time, disabling 6 OPA693ID amplifiers saves over 180 mW of dissipation on a ±5 V dual supply, extending thermal margin and battery runtime in portable video equipment.
For a compact video line driver PCB, how does the OPA693ID SOIC-8 footprint compare to alternatives in a larger package?
The OPA693ID SOIC-8 package measures approximately 5 mm x 6 mm with 1.27 mm pin pitch, making it significantly smaller than a DIP-8 footprint which spans over 10 mm x 25 mm. For high-channel-count video distribution boards where board space per amplifier must stay below 30 mm², the SOIC-8 allows 4 or more OPA693ID channels per square inch while still supporting automated SMT reflow assembly at 260°C peak temperature.
