でもまぁ16MHzのArduino R3ではこれが限界値ということで納得はできました。 USB電源ではそれなりにノイズはありますが、電池で駆動すれば残留ノイズは十分に低く、10ビットADC、サンプリングレート31.25kHzとは思えないくらいクリアです。

Analog-to-digital converters, or ADCs, are somewhat monolithic devices for most users, a black box that you ask nicely for the value on its input, and receive a number in return. For most readers, ...

Canadian electronics geek and nascent YouTuber [Technoyaki] wanted to measure 20 volt signals on his Arduino. One might typically use a voltage divider to knock them down to the 5 volt range of the ...

Using the Arduino ADC and DAC features to realize a full-fledged multichannel anayzer with only a few common components allowed to operate a used NaI scintillation counter (from Ebay) and compare the ...

Most microphones’ output signals are weak and cannot be directly connected to some other circuits. Also, some microphones require DC power supply or high impedance inputs. Here is a dual (stereo) ...

What is a Successive Approximation ADC? Successive Approximation ADC is the preferred choice for low-cost, medium to high-resolution applications. SAR ADC resolution typically ranges from 8-18 bits, ...
