Here's why I'm asking: I have a Denon AVR 3803 receiver. I like it quite a bit, except for one glaring (IMHO) omission; in order to use my Sennheiser wireless headphones, I have to run both analog and ...

A new generation of digital-input Class D audio amplifiers achieves high PSRR performance that is comparable to traditional analog Class D amplifiers. More importantly, digital-input Class D ...

The following are some basic facts about input loop power sources: The input module usually isn't a loop power source. Although 120V is common for digital loops, other voltages are also used. There ...

Serial Peripheral Interface (SPI) output driver chips are popular with embedded designers because they provide multiple outputs without using any CPU I/O pins. This article explains how to adapt a ...

The trend towards increased monitoring in industrial automation and process control requires input modules with higher channel densities. In these applications, 24V DC digital inputs (DI) make up the ...

Offering support for hi-res PCM, DSD, 7 digital inputs, and future upgradability, the McIntosh MDA200 D/A Converter warrants a serious look. 7 digital inputs and upgradability might not seem all that ...

A hardware interface that accepts only digital signals. Contrast with analog input. For various examples, see plugs and sockets. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction ...

If Rip Van Winkle were a modern-day design engineer who just woke up from his 20-year nap he would be bewildered by what has happened to oscilloscopes, the engineer’s basic design and debugging tool.

In our previous issue, we noted that the first step in troubleshooting digital input modules is to verify the power source of each loop. If input power is missing, the causes can be such things as ...
