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 ...

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 ...

[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 ...

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 ...

Engineers have reached a theoretical limit for efficiently converting analog data into digital bits in an emerging computer technology. The future of computing may be analog. The digital design of our ...
