Once more opto-isolators are to be seen in Wonderland. The aim was to see if the faster photodiode types can operate quickly in common collector mode. They consist of an infra-red led and a fast npn ...

The analog DC ammeter with an actual full-scale value of 10 milliamperes in your transmitter that measures 1 ampere of plate current has failed and the only linear meter that fits in the same space ...

The new McPherson 671MX amplifier is a high vacuum compatible, current-to-voltage converting amplifier developed specifically for use with vacuum ultraviolet Silicon photodiodes. With integral ...

Abstract: Transimpedance amplifiers (TIAs) are widely used to translate the current output of sensors like photodiode-to-voltage signals, since many circuits and instruments can only accept voltage ...

I ask these types of questions frequently. Do we need another “widget” when everybody and their grandmother makes one of these nowadays? Well, I have not seen any other amplifier that can beat the ...

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in series ...

Calculate the total resistance of the circuit. Calculate the current flowing in the \({3}\Omega\) resistor. Calculate the voltage across the \({8}\Omega\) resistor. Calculate the current flowing in ...

If you’ve played around with laser diodes that you’ve scavenged from old equipment, you know that it can be a hit-or-miss proposition. (And if you haven’t, what are you waiting for?) Besides the real ...

Almost all semiconductor products are sensitive to light, but this feature has been especially optimized for photodetectors (photodiodes and phototransistors). These are employed to sense or measure ...

Electronic allows users to view video data from CCD, CMOS and photodiode linear arrays. Easy connection to a PC or embedded systems. USB, RS232 or Parallel interface are available. Electronic allows ...

MAX4004/MAX4006 precision, high-side sensing current monitors are designed for measuring PIN photodiode current in fiber applications. Operating from a 2.7-V to 22-V supply, they are available in the ...
