Circuits & Schematics - Digital - 5

Have you ever been curious about the power consumption of an appliance? For example did you wonder how much it will cost you to leave your television in standby mode whole night? Or did you want to learn how much change your refrigerator settings ...

Application Note AN-932 2008 Martin Murnane, Chris Augusta Powering up a circuit on a printed circuit board is too often taken for granted and can cause damage and both destructive and nondestructive latch-up conditions. These problems may not be ...

John Ambrose, MSI Electronic Design Although quite a few direct digital synthesis (DDS) ICs can generate high-frequency sine waves, their complexity excludes them from many designs. However, designers can use simple high-frequency CMOS logic and ...

Utilizing the large operating voltage range of an octal CMOS buffer, this Design Idea presents a simple 8-bit two-quadrant multiplying Digital-to-Analog-Converter (DAC) built with the buffer/line-driver IC 74HC244 . Figure 1. In Figure 1, an 8-bit ...

Design Note DN522 January 2014 Guy Hoover The LTC2338 is an 18-bit fully differential SAR ADC that is remarkably easy to drive. This 1 Msps ADC operates from a single 5 V supply and achieves 4 LSB INL maximum with ­111 dB THD and 100 dB SNR. ...

Application Note AND9151/D November 2013 Creating and distributing clock signals are the heartbeat of digital systems. Today's high-end systems demand extremely low noise clock signal integrity. Jitter, and more recently, phase noise, are the most ...

James B Wood You can design a hardware-based frequency synthesizer with one inexepensive IC and a few passive components. Such synthesizer chips are not always available, however, because they are typically single-sourced and are not in stock with ...

Yury Magda A PC's serial port provides signal lines that you can use to read voltage levels of digital circuits. You can use the port to test digital TTL (transistor-to-transistor-logic)-level circuits. You just need to convert the TTL levels ...

Write Cycle This is the simplest bus cycle. Target devices detect the start of the bus cycle by the FRAME# is asserted at the second clock. At a bus cycle is initiated, the bus comand and the address is taken in to each target device attached to ...

I am 13 I have always wanted to build a cnc machine but because inexpensive parts are hard to find in Canada I have had trouble trying to build a decent cnc controller. The purpose if this Instructable is to show that anyone can build a cnc ...
