The HA5024 is four versions of the popular Intersil HA5020 . It has a wide frequency band and high slew rate, and is optimized for video applications with gains between 1 and 10. It is a current feedback amplifier and therefore produces less bandwidth degradation at high closed loop gain voltage feedback amplifiers. Low differential gain and phase, 0.1dB gain flatness, and the ability to...

For analog CMOS (Complementary Symmetric Metal Oxide Semiconductor), the two main hazards are static electricity and overvoltage (signal voltage exceeding supply voltage). By understanding these two hazards, users can effectively deal with them. Static electricity The hazard caused by the electrostatic voltage formed by the accumulation of electrostatic charges (V=q/C=1kV/nC/pF) ...

What is the use of eye diagrams in PCB design? The eye diagram is due to the afterglow effect of the oscilloscope, which overlaps the waveforms of each symbol obtained by scanning to form an eye diagram. This article will lead you to understand what the eye diagram on the PCB is, how the eye diagram is formed, what information is contained in the eye diagram, and how to distinguish the si...

The early strawberry picking machinery generally harvested the fruits and stems and leaves together, and then manually separated the fruits and stems and leaves. In 1996, Japan was the first to invent a robotic hand that uses machine vision to recognize fruit picking. The general process of picking strawberries by a robotic hand based on machine vision technology is to first look for ripe stra...
