Low Noise, Precision Op Amp Drives High Resolution SAR ADCs
12.03.2017 · Circuits
The LT6018 is an ultralow noise (1.2 nV/√Hz at 1 kHz) operational amplifier with ultralow distortion (–115 dB at 1 kHz). It has a gain bandwidth product of 15 MHz, maximum offset voltage of 50 μV and a maximum offset voltage drift of 0.5 μV/°C. This combination of features makes it suitable for driving a variety of high resolution analog-to-digital converters...
Vishay Intertechnology Native Top-View IR Receivers in Through-Hole Package Save Space in Consumer Products

Vishay Intertechnology broadened its optoelectronics portfolio with the introduction of two new series of miniature infrared (IR) receiver modules for IR remote control applications. To save space in consumer products, the Vishay Semiconductors TSOP39xxx and TSOP59xxx series devices are the industry’s first native top-view IR receivers in a through-hole package...
Simple Change Enhances Safety, Integrity of Isolated Shunt-Regulator DC-DC Converter
09.03.2017 · Articles
This Idea for Design rearranges the schematic and physical layout of an isolated dc-dc converter using a shunt regulator to overcome susceptibility to ESD and electrical overstress...
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...

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...
