Input ADC offers fault protection up to ±30 V Product News 5/31/2007 Post a comment Linear Technology released the LTC1856, a 5 V, 16-bit, 8-channel, 100 ksamples/s analog-to-digital (ADC) converter with ±10 V input ranges and additional fault protection. An overvoltage fault up to ±30 V on one or more unused channels will not corrupt the accuracy of the selected channel and provides protection on 24 V (±10% tolerance) industrial supply lines.
Regulators use I2C interface for overvoltage, overcurrent protection Product News 5/31/2007 Post a comment Intersil released the ISL6422B and ISL6423B low-noise block (LNB) supply and control voltage regulators. These regulators use an I2C interface to improve system reliability by reporting diagnostics and protecting a satellite set top box (SSTB) against overvoltage, overcurrent, overtemperature and backward current.
ADC drivers operate from single 3 V supply Product News 5/29/2007 Post a comment Linear Technology released the LTC6400-20 and LTC6401-20, ADC drivers which operate from a single 3 V supply. These fully differential amplifiers include gain-setting resistors, which aid in the driving of high-speed ADCs.

Get ready to design power for security IP cameras Design How-To 5/23/2007 Post a comment Power over Ethernet (PoE) is fast becoming the networking vehicle of choice for video surveillance cameras. As the IEEE works to increase the power available to network powered devices, the market is expected to have new momentum to increase this explosive growth. Find out what you need to know for creating power supplies appropriate for your applications.
Teridian launches single-package DAA modem device Product News 5/23/2007 Post a comment Check out Teridian's pair of modem chipsets, one of which it claims is the first single package silicon direct access arrangement (DAA) product that uses an inexpensive common pulse transformer to form a digital isolation barrier.
Intel-ST deal: What it means News & Analysis 5/23/2007 Post a comment Now that Intel and STMicroelectronics have finally sealed the deal, here's a look at how the deal measures up and what it may mean for the rest of the industry.
Chip brands failing Intel, AMD News & Analysis 5/22/2007 Post a comment What's in a name? Apparently not much, according to one survey that finds chip brands don't register as well with consumers as companies might think.
Boost regulator offers high-current output, fault protection Product News 5/18/2007 Post a comment Intersil released the ISL97701; a boost regulator which provides a design for passive matrix OLEDs. With efficiency up to 87%, the ISL97701 can deliver 50 mA of output current at 18 V. It can provide up to 28 V output, enabling power-efficient operations in MP3, portable media players, automotive clustering and low-end cell phones PMOLED displays.
LDO linear regulator offers quiescent current of 3µA Product News 5/18/2007 Post a comment Linear Technology developed the LT3009, a micropower low dropout voltage (LDO) linear regulator with low quiescent current of 3µA. The LT3009 features a low-dropout voltage of 280 mV and delivers up to 20 mA of output current, with a VIN capability of 1.6 V to 20 V and an adjustable output from 0.6 V to 19.5 V.
H.264 video encoder motion search implementation on a programmable accelerator Design How-To 5/18/2007 Post a comment H.264 video encoding supports the movement of a reference block in 41 possible motion vectors, but calculating all possibilities requires significant number crunching. Stretch's high-performance motion search engine computes all 41 possible H.264 motion vectors for a 16x16 macroblock at a sustainable rate of 250 MB-SADs (macroblock sum-of-absolute-differences computations) per second. How it works.
ADCs operate at temperature up to 125°C Product News 5/17/2007 Post a comment Linear Technology developed the LTC1403AH, a 14-bit, 2.8 Msamples/s SAR ADC which operates over the automotive -40°C to +125°C temperature range. The LTC1403AH is powered from a single 2.7 V to 3.6 V supply, draws 14 mW at 2.8 Msamples/s, and is available in a small, 10-lead MSOP package.
