At the Intel IDF2014 technical conference for makers, developers, and creators held in San Francisco last week, you got the sense that analog is the new revolution in digital. From the Internet of Things to wearable computing to smart consumer products, sensors play a rapidly growing role in those billions of connected devices acquiring, transmitting, and analyzing data — Big Data. Intel’s […]

Texas Instruments (TI) (NASDAQ: TXN) expanded its broad portfolio of industry-leading sensing integrated circuits (ICs) with four new devices that allow engineers to accurately sense key parameters in tight spaces with very low power. These new products provide solutions for temperature, humidity, ambient light and capacitive sensing in a host of industrial and enterprise applications. […]
Camera flash LED driver delivers 1.2A
Micrel, Inc. introduced the MIC2873/MIC2874, an ultra-compact, camera flash LED driver that integrates a 1.2A boost converter and LED driver circuit into a small 9 pin, 1.3mm by 1.3mm chip scale package. Operating from 2.7V to 5.5V and featuring up to 92 percent efficiency, these solutions are ideally suited for Li-Ion battery operated portable applications […]
100-V forward converter outputs regulated 12 V without optocoupling
Linear Technology Corporation announces the LT8310, a primary-side synchronous forward controller. The LT8310 operates over an input voltage range of 6V to 100V, is targeted for power levels up to 200W and provides a drive signal for secondary-side synchronous rectification to improve efficiency. Output voltage regulation of ±8% can be attained without the use of […]
Diode array filters target differential line pairs
Littelfuse, Inc. has introduced the SP5001, SP5002, and SP5003 Series TVS Diode Arrays (SPA® Diodes). These highly integrated Common-Mode Filters (CMF) provide both electrostatic discharge (ESD) protection and common-mode EMI filtering for systems that use high speed differential serial interfaces. They can protect and filter two (SP5001 and SP5003) or three (SP5002) differential line pairs. […]
IO-Link transceiver includes integrated step-down regulator & LDO
The LT3669 is an IO-Link PHY compatible (COM1/COM2/COM3) industrial transceiver that includes a high efficiency step-down regulator and a low dropout linear regulator. The device offers cable interface protection to ±60V. Wake-up detect functionality as well as a programmable power-on reset timer are included for system reliability. The LT3669/-2 operates from a 7.5V to 40V […]
Using LTspice for power supply design
Simulation using a SPICE simulator (Simulation Program with Integrated Circuit Emphasis) is handy for checking out designs before building them as well as helping to understand designs and circuit problems. You can experiment without blowing anything up! LTspice from Linear Technology is particularly useful as it is free and available to download from their web […]
Analog filters
Filters are an important part of analog design. Even circuits that you don’t think of as filters are actually filters. For example, a simple amplifier will have a bandwidth and so above its upper 3dB point it is a low pass filter. Whole books have been written on filters and filter design, both analog and […]
