Cool Summer Free Article of the week: 16-bit Data Logger

To make accurate voltages measurements you need an A/D converter (ADC) chip which has good resolution. The folks at Elektor Labs have developed a board containing a four-channel 16-bit ADC. It’s no coincidence the board uses a Gnublin/EEC connector which makes it compatible with the Elektor’s Linux board, Xmega Webserver and the new Extension shield for Arduino. A universal C library is included to make integration a walk in the park.

Microchip announces a family of compact Analogue-to-Digital Converters (ADCs) that offer high programmable data rates of up to 153.6 kilosamples per second (kSPS).

This is a submission from Microchip about 12 new Successive Approximation Register (SAR) Analogue-to-Digital Converters (ADCs) together with a companion differential amplifier designed specifically for the new portfolio of SAR ADCs.

Data conversion solutions are important elements in high-speed aerospace systems. Recent advances high-speed data converters are revolutionising the design of systems for space exploration.

I wrote previously that it is hard to pass the EXIT / AUSGANG gates at the embedded world trade show in Nuremberg and not have a few demo or dev kits in your sponsored rucksack. That’s why the show is a must-attend for serious electronicists of all ages. I consider myself one but this year I was unable to attend the show and what do you think, I still I received a kit — it simply arrived in the mail a few days later. It is the Otii Arc Demo kit from IoT developers Qoitech in Sweden hence the polar bear on the box. On the Arc box proper I saw “Sony Belgium” printed.

A new dual 14-bit A/D converter (ADC) designed to support communications applications capable of direct sampling wide bandwidth analog signals of up to 5 GHz has a −3 dB bandwidth of 9 GHz. The ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. The device’s inputs support a variety of user-selectable input ranges while an integrated voltage reference simplifies the use of the part.

A while back we made a little break-out-board with a ADS1115 A/D converter (140169-1). It has four inputs that can be used in a single-ended mode or two inputs can be used in a differential mode. A project still in development is a power meter for mains powered appliances.
