60V Buck-Boost LED Driver with Up to 98% Efficiency Has Internal PWM Dimming and Spread Spectrum
10.27.2016 · Circuits
Synchronous buck-boost converters with four power switches can deliver very high efficiency while providing both step-up and step-down DC/DC conversion. Combining the capabilities of two separate converters (buck and boost) has the advantage of reduced solution size and cost. Four-switch converters should be able to operate with just two switches for highest efficiency when only step-up or step-down conversion is needed. However, they must also be able to utilize four-switch operation...
Analog Devices' Low Power AFE Enables Smaller, Lighter Wearable Health Devices with Longer Battery Life
10.27.2016 · News
Analog Devices announced a low power, next-generation biopotential analog front end (AFE) which enables smaller, lighter, and less obtrusive cardiac monitoring devices with longer battery life. The AD8233 AFE is a fully integrated, single-lead electrocardiogram (ECG) front end designed in one compact, easy-to-use component. Typically, developers need to design ECG front ends from individual components, which can add incremental cost and design time...
Keyboard and display multiplexing - Charlieplexing
After my previous review of more traditional ways of reducing the I/O lines needed to drive LEDs/displays and keyboards/switches, here I'm looking at the nominally new method of Charlieplexing...
Silicon Labs Launches Industry's First Custom Solid-State Relay Solution Based on CMOS Isolation Technology
10.26.2016 · News
Silicon Labs has introduced a groundbreaking CMOS-based isolated field effect transistor driver family that enables developers to use their choice of application-specific, high-volume FETs to replace outmoded electromechanical relays and optocoupler-based solid-state relays. The new Si875x family features the industry’s first isolated FET drivers designed to transfer power across an integrated CMOS isolation barrier, eliminating the need for isolated secondary switch-side power supplies and reducing system cost and complexity...
TI unveils first ultra-low power dual-band wireless MCU in production
Expanding the functionality of Internet of Things networks, Texas Instruments announced availability for mass production of the industry's lowest-power dual-band wireless microcontroller supporting Sub-1 GHz and Bluetooth® low energy connectivity on a single chip. As part of TI's pin-to-pin and software compatible SimpleLink™ ultra-low power platform, the new SimpleLink dual-band CC1350 wireless MCU enables developers to move from a three-chip solution to a tiny single chip, while reducing design complexity, saving power, cost and board space...
Forced quenching improves three-transistor FM tuner
10.24.2016 · Circuits
The idea of using a super-regenerative radio to receive commercial FM stations can be found at various locations on the Internet. Because the circuit is so small, it might be impressive to lab visitors, especially to children. But the basic one-transistor circuit has drawbacks; a better circuit is the subject of this Design Idea...
Analog Devices' MEMS Accelerometers Enable Early Detection of Structural Defects
10.24.2016 · News
Analog Devices, Inc. (ADI) announced three-axis, MEMS accelerometers that perform high resolution vibration measurement with very low noise to enable the early detection of structural defects via wireless sensor networks. The low power consumption of the new ADXL354 and ADXL355 accelerometers lengthens battery life and allows extended product usage by reducing the time between battery changes. The low noise performance of the ADXL354 and ADXL355 with low power consumption makes it now possible to cost-effectively enable low-level vibration measurement applications...
