Cryptography tool protects products and integrates with 1-Wire
Analog Devices, Inc. introduced the DS28E30 1-Wire ECDSA Secure Authenticator, a cost-effective solution to detect and help protect products from counterfeiting or misuse. Combining a fixed-function cryptographic toolbox based on the industry-standard FIPS 186 elliptic curve digital signature algorithm (ECDSA), secure storage of keys and application data, and the single-contact 1-Wire interface, the device easily […]
Analog front end reduces, size, extends life of remote-patient monitoring devices
Reduce the size and extend the life of bioimpedance (BioZ) remote-patient monitoring (RPM) devices with the MAX30009 low-power, high-performance BioZ analog front-end (AFE) from Analog Devices, Inc. (ADI). For developers of small, battery-powered, continuously wearable devices, this AFE on a chip offers clinical-grade vital sign measurements of bioimpedance analysis for patient health assessment for wellness wearables and […]
Stress & Strain, Part 2: Implications for electronics
The mechanical strain induced on electronic components due to mechanical and thermal stress is an important aspect of their performance consistency and limitations; stress is also used to enable some materials to provide critical electronic functions. Part 1 of this FAQ looked at the basic principles and tests for material strain when stress is applied. […]
Stress & Strain, Part 1: fundamental principles
The mechanical strain induced on electronic components due to mechanical and thermal stress is an important aspect of their performance consistency and limitations; stress is also used to enable some materials to provide critical electronic functions. Although electronic systems and circuits invoke intangibles such as voltages, currents, power, EM fields, and Maxwell’s equations — to […]
Smoke detector reference design and algorithm is UL217-tested and verified
Analog Devices, Inc. (ADI) introduced a reference design and algorithm that enables small form factor, low power, smoke detector designs to be rapidly prototyped and brought to market faster at a reduced cost. The new CN0537 reduces design risk and has been tested and verified to pass the UL 217 Standard for Smoke Alarms, 8th […]
Filters, Part 1: Analog, switched, and digital filters
Filters are essential functions in most circuits and systems; as frequencies extend into the multi-GHz range, surface acoustic wave (SAW) and bulk acoustic wave (BAW) filters are needed to meet the design objectives. An engineer I worked with (and whose name I have forgotten) once remarked to about electronic filters (and he was serious): “like […]
Hardware/software combo leverages audio bus technology to deliver hi-fi multichannel digital audio
Analog Devices, Inc. (ADI) introduced today a full audio system that features the SHARC Audio Module (SAM) for the creation of digital audio devices, including audio FX processors, multi-channel audio systems, MIDI synthesizers, and other DSP-based audio systems. SAM includes the dual-SHARC+ core ADSP-SC589 audio processor SoC (with an integrated Arm Cortex-A5 core) and leverages […]
