- What are some common applications of the ADC1173?
Common applications include video digitization, digital still cameras, set top boxes, camcorders, personal computer video, digital television, CCD imaging, and electro-optics.
- How does the ADC1173 handle power supply noise?
The ADC1173 requires careful power supply bypassing to prevent noise corruption. A 10µF tantalum or aluminum electrolytic capacitor and a 0.1µF ceramic chip capacitor should be used for each supply pin.
- Can the ADC1173 operate with different clock frequencies?
Yes, the ADC1173 can operate with clock frequencies from 1 MHz to 20 MHz, although it is typically tested at 15 MHz.
- How does the ADC1173 reduce power consumption when not in use?
Power consumption can be reduced by stopping the clock at a logic low when the ADC1173 is not being used, which reduces the current drain in the digital circuitry.
