The usual method of bringing analog inputs into a microprocessor is to use an analog-to-digital converter (ADC). Here are some tips for selecting such a part and calibrating it to fit your needs. In ...

It’s a well-known conundrum that while most computers these days are digital in nature, almost nothing in nature is. Most ...

All analog-to-digital converters (ADCs) have a certain amount ofinput-referred noise. In most cases,less input noise is better. There are some cases, however, where inputnoise can actually be helpful ...

In the Op Amp circuit shown in the figure, let Rf = 10kΩ, R1 = 10kΩ, R2 = 20kΩ, R3 = 40kΩ, and R4 = 80kΩ. Obtain the analog output for binary inputs [0000], [0001], [0010], . . . , [1111]. Using this ...

Energy-efficient successive approximation register (SAR) analog-to-digital converters (ADCs) represent a rapidly evolving field in microelectronics, where substantial progress has been made in ...

If you’ve ever listened to an MP3, watched a movie on Netflix, or jumped on a Zoom call, you’ve used a DAC. Digital-to-analog converters (or DACs for short) are the unsung heroes of the digital audio ...

Nobody will cry when the static dies. “Analog” television — those grainy, sometimes static-filled broadcasts — will end on Feb. 17, 2009. That’s the date that the Federal Communications Commission has ...
