The Pixel 2.0 is a tiny OLED screen for your wearable Arduino pleasure
The tiny Pixel 2.0 is basically an Arduino board wedded to a tiny 1.5″ 128×128 color OLED screen. This means you can stick it inside a wearable and address the screen directly from the Arduino board, an improvement on current “solder the screen to the Arduino and hope it works” world of DIY electronics. This teeny-weeny board costs $75 on Kickstarter and should ship in June...
300MHz to 6GHz Dual Wideband Mixer with Programmable Gain Amplifiers Enables 5G Wireless Access
09.03.2017 · News
Linear Technology introduces the LTC5566, a new wideband, high dynamic range dual channel mixer with integrated programmable variable gain IF amplifiers. This dual mixer has a very wide, 300 MHz to 6 GHz input frequency range, specifically optimized and with extensive characterization at the emerging 3.6 GHz and 4.5 GHz 5G bands, as well as the established 4G bands...
Thermal switches provide circuit disconnect
08.03.2017 · Circuits
A single temperature sensor can provide an interrupt to a microcontroller when the measured temperature goes out of range. You need multiple temperature sensors when you have to monitor more than one hot spot. A microcontroller implements the proper protective action when one of the temperature monitors detects an overtemperature condition...
Epson Shipping Samples of a New 16-bit Microcontroller with a Crystal Unit and High-Precision Temperature-Compensated RTC
Seiko Epson Corporation has begun shipping samples of the S7C17M11, a low-power 16-bit microcontroller with on-chip Flash memory, a crystal unit, and a highly accurate real-time clock...
Nano Dimension, in Collaboration with the Israeli Ministry of Defense, Receives Grant to Develop 3D Printing of Ceramic Materials, Designated for the Aerospace and Aviation Sectors
08.03.2017 · News
Nano Dimension Ltd. announced that its wholly owned subsidiary, Nano Dimension Technologies Ltd., has received a budget from MEIMAD committee of the Israel Innovation Authority which will be used to finance a project to develop 3D printing of advanced ceramic materials in inkjet technology...
RC oscillator generates linear triangle wave
07.03.2017 · Circuits
This Design Idea avoids the RC charging waveshape of a standard relaxation oscillator, replacing it with a linear rise/fall triangle wave. Positive feedback is used to increase the charging rate over each half-cycle and straighten out the curve...
MAX232: The classic IC lives on since 1988
07.03.2017 · Articles
The June 23, 1988 issue of EDN included a Maxim Design News insert where we asked "Who in their right mind would choose a computer interface standard that uses ±12 V supplies, requires expensive connectors, works over a limited distance, is error prone, difficult to network, and has no current loop isolation?" Yet, here we are 28 years later and the classic interface lives on...
Rail-to-Rail Op Amps Feature Precision & Power Efficiency
07.03.2017 · News
Linear Technology introduces the LTC6258/59/60 and LTC6261/62/63, single/dual/quad op amps, extending its line of power efficient, low noise, precision operational amplifiers. These devices are part of a family of power efficient op amps ranging from 1.3 MHz GBW product at 20 μA supply current to 720 MHz GBW product at 3.3 mA supply current...
Instrumentation amplifier is less sensitive to resistor mismatch
06.03.2017 · Circuits
This Design Idea offers a new instrumentation-amplifier topology that improves ac CMR (common-mode rejection). Because it uses discrete amplifiers, you can customize it for the lowest power, price, noise, and supply voltage, depending on your application’s requirements...
TI unveils industry's smallest 12-V, 10-A DC/DC step-down power solution
06.03.2017 · News
Texas Instruments introduced a pair of 12-V, 10-A, 4-MHz step-down power modules that provide a power management solution that is 20 percent smaller than any other 10-A power module-based solution available today. The easy-to-use SWIFT TPSM84A21 and TPSM84A22 DC/DC modules integrate power MOSFETs, shielded inductors, input and output capacitors, and passives...
