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.

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.
