NXP shrinks power transistor design for mobiles
These miniature devices are designed for energy efficiency and low heat dissipation. When mounted on a 4-layer PCB, the thermal performance is designed to match that of larger SMD packages
TI intros its lowest noise octal 12-bit ADC
The ADS5294 has specified signal-to-noise ratio (SNR) of 75.5dBFS at 5MHz
Rohm has single chip USB audio decoder
As USB and SD memory cards become the de facto storage medium for audio and multimedia files. Rohm has a range of single-chip USB audio decoders for different file formats
NASA uses e2v imagers to measure the ozone layer
The imaging sensors are used in the Ozone Mapping and Profiler Suite of instruments which measure the ozone by collecting light from the sun that has been reflected off of the atmosphere
ADI moves MEMS gyro sensor to tactical grade
Analog Devices has introduced a new MEMS IMU (inertial measurement unit) in its iSensor range and the signficance is this is a tactical grade 10-degree-of-freedom (DoF) sensor
NXP outlines ‘best’ technology for military RF up to 3.8GHz
High voltage LDMOS (laterally diffused metal oxide semiconductor) is the optimal technology choice for defence and avionics RF power applications up to 3.8GHz
Scottish chip firm Wolfson improves audio in smartphones
The Scotland-based firm said it tackles the audio quality issues caused by routing analogue signals over longer distances
ZMDI uses digital chip to improve MEMS sensor accuracy
"Responding to sensor system designer needs, we have developed a digital technique to correct both first-order and third-order nonlinearity errors," said Steve Ramdin, product manager at ZMDI
Memsic improves vineyard yields
Increasing vineyard yields is important work and Memsic, the Massachusetts MEMS specialist, has found a way to do that with wireless sensor networks.
