Datenerfassungs-IC von Analog Devices vereinfacht Industrie- und Instrumentierungs-Design

Analog Devices, Inc. (ADI), der Weltmarktführer auf dem Gebiet der Datenkonversionstechnologie*, stellte heute einen hochintegrierten Datenerfassungs-IC (integrierter Schaltkreis) vor, der ein Drittel des Platinenplatzes konkurrierender diskreter Bauelemente benötigt, um Ingenieure dabei zu unterstützen, das Design zu vereinfachen und die Größe moderner industrieller Datenerfassungssysteme zu reduzieren. Der neue 16-Bit, 1-MSPS (Megasamples pro Sekunde) ADAS3022 Datenerfassungs-IC wurde für die Überwachung von Stromleitungen, Prozess- und Motorsteuerung, Patientenüberwachung und andere Industrie- und Instrumentierungssysteme, die innerhalb des ±10-V-Bereichs betrieben werden, konzipiert.

„Mit einem dominanten globalen Datenkonversions-Marktanteil von etwa 48,5 Prozent im Jahr 2011 wird Analog Devices von dem Branchenanalysten Databeans als führende und wegweisende Kraft auf dem modernen Datenerfassungs- und Signalaufbereitungsmarkt angesehen. Mit einzigartigen neuen Produkten, wie dem ADAS3022, der äußerst hohe Leistungswerte bei geringeren Abmessungen verspricht, bleibt Analog Devices beispielgebend für viele bedeutende Verbesserungen, die diese dynamische Branche voranbringen”, erklärte Matthew Scherer, Marktanalyst bei Databeans Inc. „Databeans ist überzeugt, dass Analog Devices aufgrund dieser Produktfreigaben hervorragend aufgestellt ist, um seine führende Position in diesem Marktsegment auch in den nächsten Jahren behaupten zu können.”

Der ADAS3022 Datenerfassungs-IC integriert den 16-Bit PulSAR® A/D-Wandler-Kern nach dem Wägeverfahren (sukzessive Approximation) mit hochohmigen Eingabepuffern und einem 7-stufigen auf dem Chip befindlichen PGIA (programmierbarer Messverstärker). Der ADAS3022 verfügt über einen 8-Kanal-Multiplexer mit niedrigen Verlustströmen und eine 4,096-V-Präzisions-Spannungsreferenz mit niedriger Abweichung. Mit acht Datenkanälen und der Bereitstellung des gesamten 16-Bit-Dynamikbereichs wurde der neue IC optimiert, um eine Kopplung mit einer Vielzahl von Sensoren zu unterstützen, die in den Bereichen von ±10 V bis zu ±640 mV betrieben werden.

Der ADAS3022 bietet eine vollständige werkseitig kalibrierte und geprüfte Signalkette und erfüllt alle Anforderungen in Zusammenhang mit Einschwingzeiten, Signalpufferung, Level-Shifting, rauscharmer Verstärkung/Rauschunterdrückung und Analogsignalaufbereitung, die früher zu dem Standardaufgabenprofil des Systemdesignprozesses gehörten.

Empfohlene ergänzende Komponenten

Zu den ergänzenden Komponenten für den ADAS3022 gehören die ADR381 Bandgap-Spannungsreferenz, ADR434x XFET Spannungsreferenz, ADR454x extrem rauscharme Spannungsreferenz, der ADP1613/14 Aufwärts-PWM-Schaltwandler, ADP1715 Linearregler, ADP3334 Linearregler, ADP7102/04 CMOS rauscharmer LDO, AD8031/32 Referenzpuffer mit geringem Energieverbrauch und ADA4841 ADC-Treiber mit geringem Energieverbrauch für ein Hilfseingangspaar (AUX±). Ein Evaluation-Board steht ebenfalls zur Verfügung, das die Systementwickler in die Lage versetzt, den ADAS3022 ohne Einsatz einer Leiterplatte oder Änderungen am Softwarecode konfigurieren zu können.

Ask someone to architect an Internet of Things (IoT) solution and you are guaranteed to see a reference to the cloud. This would lead you to believe that IoT requires the cloud to exist. However, there are many IoT use cases where the cloud is not feasible or desirable. In his session at @ThingsExpo, Dave McCarthy, Director of Products at Bsquare Corporation, will discuss the strategies that exist to extend intelligence directly to IoT devices and sensors, freeing them from the constraints of ...
You think you know what’s in your data. But do you? Most organizations are now aware of the business intelligence represented by their data. Data science stands to take this to a level you never thought of – literally. The techniques of data science, when used with the capabilities of Big Data technologies, can make connections you had not yet imagined, helping you discover new insights and ask new questions of your data. In his session at @ThingsExpo, Sarbjit Sarkaria, data science team lead ...
Extracting business value from Internet of Things (IoT) data doesn’t happen overnight. There are several requirements that must be satisfied, including IoT device enablement, data analysis, real-time detection of complex events and automated orchestration of actions.

IoT generates lots of temporal data. But how do you unlock its value? You need to discover patterns that are repeatable in vast quantities of data, understand their meaning, and implement scalable monitoring across multiple data streams in order to monetize the discoveries and insights. Motif discovery and deep learning platforms are emerging to visualize sensor data, to search for patterns and to build application that can monitor real time streams efficiently. In his session at @ThingsExpo, ...
Early adopters of IoT viewed it mainly as a different term for machine-to-machine connectivity or M2M. This is understandable since a prerequisite for any IoT solution is the ability to collect and aggregate device data, which is most often presented in a dashboard. The problem is that viewing data in a dashboard requires a human to interpret the results and take manual action, which doesn’t scale to the needs of IoT.

Much of IT terminology is often misused and misapplied. Modernization and transformation are two such terms. They are often used interchangeably even though they mean different things and have very different connotations. Indeed, it is somewhat safe to assume that in IT any transformative effort is likely to also have a modernizing effect, and thus, we can see these as levels of improvement efforts. However, many businesses are being led to believe if they don’t transform now they risk becoming ...
