In our previous two issues, we discussed troubleshooting digital output modules. Troubleshooting analog modules is a bit more complicated, for two reasons: Analog modules aren't on/off, as digital ...

Quadrature digital upconverter is more than DDS+DAC. The AD9856 digital upconverter (Figure) takes a complex, 12-bit data word representing I and Q data from your source, demultiplexes the word into I ...

The ADC is a common analog building block and almost always is needed when interfacing digital logic, like that in an FPGA or CPLD, to the 'real world' of analog sensors. This article will explain the ...

The analog MEMS microphone typically renders a reasonable signal level with a fairly low output impedance. So, it is convenient if it will be linked to the input of an analog signal processing ...

All modules operate from -40 to +60°C with noise immunity, surge protection, high shock and vibration tested, and CE compliance. UL/cUL Class 1 Division 2 Zone 2 hazardous location approval is pending ...

Even with a 24-bit digital system, the noise floor (as measured at the output side of the console) will be limited by the noise floor of the analog mic preamp; the noise floor measured for the means ...

The output DACs are 16-bit, have 16 lines of digital I/O, and have one 32-bit counter timer at 1-MHz to measure events. Prices range from $605 for a 4-channel voltage-output model to $815 for an 8 ...

1. The MAXREFDES177# design joins analog I/O to IO-Link by blending a universal analog I/O IC with an IO-Link transceiver IC, yet separated by a digital-galvanic isolator.

From these components, it's easy to see how you could build an Analog-to-Digital converter or a Digital-to-Analog converter. The only variable input I found useful for analog input was the Slider. The ...

Microcontrollers are digital devices at heart. They can do fancy things like convert analog signals into a digital value but going the other direction is a bit tougher. Pulse-Width Modulation is us… ...

In previous issues, we have discussed troubleshooting input modules. In the examples, the output modules checked out OK. But what if they don't? As with input modules, output modules can be digital or ...
