										Hams, Broadcast Engineers, And Cancer-Causing Smart Meters

										 Don Tuite, Analog & Power Editor

											Should consumers with smart meters be worried about the RF fields they emit? The Electric Power Research Institute recently released a report noting that the RF fields surrounding smart power meters are well below what the Federal Communications Commissions allows. And if that isn’t convincing enough, take a look at ham radio operators and broadcast engineers, who have been around a lot more RF energy than the average smart-meter owner.

																Bridging the Divide: A DAC Applications Tutorial

DACs are designed in a wide spectrum of applications. While IC manufacturers are integrating more features into a microprocessor or FPGA every year, there will always be some type of analog conversion for interfaces. Read the article to learn more about common DAC applications such as calibration and motor control. Brought to you by National Semiconductor. Read now.

										High-Voltage Electric/Hybrid Vehicle Battery Monitor Chip Evolves

										 Don Tuite, Analog/Power Editor

											To minimize conduction losses in the propulsion system, battery packs for hybrid and all-electric vehicles stack low-voltage cells and battery modules to achieve high voltages. Reporting all the voltages in these series stacks can be tricky, but the Linear Technology LTC6803 can be designed into those battery packs to monitor up to 12 individual battery cells in series.

										New Apps Help Push Power IC, Discrete Markets

										 Ron Schneiderman, Contributing Editor

											Pushed by new applications and a growing emphasis on power management, some vendors believe the power IC and discrete markets could grow as much as 15% this year. But that calls for them to come up with more efficient, more highly integrated, and even smaller products.

										Light-Sensing Circuit Yields Human-Like Dynamic Range

										 Stephen P. Hendrix, Hx Engineering

											Photodiodes and phototransistors, whether photoresistive or photovoltaic, respond to a wide range of light levels by producing a current (not voltage) that is, unfortunately, linearly proportional to the light (as long as you keep the voltage bias constant or nearly so). We have to do something additional to obtain the desired logarithmic behavior. Fortunately, a logarithmic relationship is hidden in the humble PN junction.

										30-V N-Channel And 20-V P-Channel MOSFETs Feature Low Profile

										 MD&D News Staff

											Targeting handheld devices, the Vishay SiA444DJT MOSFET features a 0.6-mm profile, and the SiA429DJT MOSFET features low on-resistance for a p-channel device with a sub-0.8-mm profile.
