New Power Management Controllers - SC457 and SC458 - from Semtech
Semtech has announced the SC457 and SC458 power supply controllers with digitally controlled output and fast transient performance for processors and graphics chips used in notebook computers. With a built-in 7-bit DAC, the output voltage of the SC457 and SC458 can be digitally programmed in 12.5 mV steps from 0.3V up to 1.5V for precision control over output voltages.
16-bit Op Amp offers very low distortion
Texas Instruments has introduced an expansion of its high-performance family of fully-differential amplifiers that drive high-speed and high-resolution analog-to-digital converters (ADC). Designed for high accuracy 3.3V to 5V data acquisition systems, the new wideband device offers rail-to-rail output and provides both low noise and the lowest distortion for demanding applications such as wireless communication, test and measurement and medical i...
Hi-Speed Multi-Media Switch Integrates USB and Audio Switching Capability
Fairchild Semiconductor’s highly integrated multi-media switches offer an industry-leading combination of features, performance and packaging for a range of portable applications. The new devices integrate both USB and negative swing (low-distortion) audio switching functionality into a single package. This integration enables portable applications to handle either USB or audio signals via one connector and helps designers eliminate the need f...
Multiplexers transmit quality audio video and high-speed USB
Intersil has introduced a family of dual 2:1 multiplexers that enable the transmission of quality audio, video, and high-speed USB data through a single input/output port, eliminating up to two ports on each portable device.
Triple Video Amp with Integrated Filters and HV Sync Capability
Texas Instruments has introduced the first video amplifier with integrated filters that is capable of handling both analog RGB signals and digital horizontal and vertical (HV) sync signals on a single chip. The new device saves up to 80 percent board space when compared to traditional amplifier solutions for video projectors, professional video, broadcast video, computer display, traditional and digital TV systems. In addition, designers benefit ...
ADI's precision battery monitor family prolongs automotive battery life
Analog Devices has announced its ADuC703x family of highly integrated, precision battery monitors. With the increasing volume of electronic content in today’s cars, coupled with the fact that 60 percent of all automotive electronics failures can be attributed to faulty or discharged batteries (according to The Allgemeiner Deutscher Automobil-Club), there is a growing need to continuously monitor battery capacity and intelligently manage power ...
Clock IC provides all critical timing functions on one chip
Analog Devices is introducing what it says is the the industry’s first clock IC to combine low phase noise clock generation with 14-channel clock distribution at jitter levels below 1 picosecond. The AD9516 series integrates an integer-N synthesizer, two reference inputs, a voltage-controlled oscillator (VCO), programmable dividers, adjustable delay lines and 14 clock drivers, including LVPECL, LVDS and CMOS.
Hall-effect sensor ICs for battery-powered applications
The new A1391 and A1392 linear Hall-effect sensor ICs from Allegro MicroSystems Europe are micropower devices that feature a power consumption of only 10 mW in active mode. Despite the low power consumption, the features required to produce a highly accurate linear Hall effect IC have not been compromised.
ST's 3-Axis Accelerometers feature small form factor and low power consumption
STMicroelectronics has introduced the first two devices in its new family of low-g linear accelerometers, distinguished by small form factor and low power consumption. The feature-rich LIS302 sensors meet the growing demand for smart functionality, such as hard-disk drive protection and motion-controlled operation, in today ’s mobile phones, digital audio players, and laptops.
Quad-channel Parametric Measurement Unit
Analog Devices is introducing the industry’s first quad-channel PMU (parametric measurement unit). The AD5522 combines four independent channels in a space-saving 12 mm × 12 mm TQFP package. Each of the four channels includes on-chip sense resistors for 5 microamp, 20 microamp, 200 microamp and 2 milliamp current ranges.
