transistor. In this example, the NPN transistor needs to drop around 5V across it, which would limit it to a maximum of -100mA average load current (note: the peak gate charge/discharge current is supplied from the output capacitors, so only the average current drain needs to be considered...
Designers do not necessarily have to be experts in setting up a PCB manufacturing plant. However, it’s a value addition to be familiar with the fabrication process and its impact on circuit board layout design. Knowledge ofPCB manufacturingandcircuit board assemblycan help you anticipate and prev...
drop the SMD parts into place, put in the reflow oven and bake. You don't even have to be all that precise in positioning the SMD parts as the
I2C devices are are 3.3V these days. “In general, in a system where one device is at a higher voltage than another, it may be possible to connect the two devices via I2C without any level shifting circuitry in between them. The trick is to connect the pull-up resistors to the lower...
If your power supply doesn't work, you'll need to find a new replacement online and replace the entire unit. This is fairly easy: to do so, remove the three Torx screws holding the power supply down, disconnect its connector from the motherboard, then slowly peel it up from its sticky...
“seen” by the receiver continues to rise throughout the course of the first three bits. This takes the signal above its “median” value, which means that even when the signal returns to its 010101. . . sequence, the receiver will actually continue to “see” a never-ending series of...
It is important to take high margin when a low-path filter is calculated. In this case, the cutoff frequency is fixed to 33 MHz to not attenuate the input signal. To equilibrate the input bias current on both input pins of the op amp, t...
This module needs 5V for VCC but can accept an IN signal from 3V–12V so it works great with our 3.3V logic directly. For better stability though, it is advisable to use an NPN transistor circuit to adjust the logic level. Important Notes ...
