Precision 36V Amplifiers with Low Power and Small Size
Texas Instruments has introduced two precision operational amplifiers that combine ultra-low noise with lower power, smaller package size and higher bandwidth than competitive 36-V amplifiers. The OPA211 and OPA827 enable breakthrough performance for test and measurement, instrumentation, imaging, medical, audio and process control applications. These are the first devices developed using TI's groundbreaking BiCom3HV complementary bipolar 36-V si...
Highest Bandwidth 4:1 Multiplexer for High-Performance Analog Applications
Fairchild Semiconductor has introduced the FHP3194, a 1.2GHz 4:1 analog multiplexer. Boasting an 800MHz small-signal and 500MHz large-signal -3dB bandwidth (at G=2), the FHP3194 offers approximately 25 percent higher bandwidth than comparable devices. This performance makes it the only multiplexer on the market today with the bandwidth capable of exceeding the high-resolution requirements for high-definition (HD), 1080p and 1080i, and PC graphic ...
Intersil launches multiplexer that allows switching between four different input signals for video applications
Intersil introduced the ISL59446, a triple-channel 4:1 multiplexer that allows the user to switch between four different input signals such as RGB or YPbPr (the colour space used in video electronics). The device allows customers to replace multiple muxes, simplifying design and saving board space.
ADI introduces ADP1653 high-efficiency, high-brightness, dual, white LED driver
Analog Devices, Inc. is introducing a white LED driver for the camera-phone flash function that uses a new portable power management technique to maintain picture quality even when the battery is taxed by multiple phone functions operating simultaneously.
Allegro's A138X Programmable Hall sensor ICs are low profile
The new A138X family of Hall-effect sensor integrated circuits from Allegro MicroSystems Europe are programmable, analogue-output devices that are offered in a choice of low-profile surface-mount packages.
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 ...
