A great many industrial sensors — flow, level, temperature, pressure, pH, and the list goes on — produce a 4-20 mA output, but today's factories increasingly need digital inputs via standard field ...

[Daniel Garcia] sent us a quick tutorial he put together demonstrating how to use an ATmega168 to perform analog to digital conversions. This timely tutorial would make for a nice complimentary ...

Traditionally, "ping-pong" configurations have been used with sample-and-hold circuits to increase throughput rates in data-acquisition systems. To increase throughput, this same technique can be ...

Did You Know? The “real” world we are living in is Analog! Whether it is sound, light, temperature or humidity, all are continuously varying things. However, when we want to communicate with the ...

Low-cost, 8-bit, single-chip microcontrollers are stingy when it comes to on-chip PWM (pulse-width-modulation) resources. The use of a PWM resource often forces a designer to sacrifice a ...
