National Semiconductor Introduces First Stereo Analogue Subsystem for Mobile Handsets with Class G Headphone Amp and Loudspeaker Protection
National Semiconductor announced the industry’s first stereo analogue subsystem with integrated Class G headphone amplifier and automatic level control (ALC) for smartphones and feature phones. The PowerWise LM49251’s Class G headphone amp dynamically reduces the supply voltage to lower power consumption and extend audio (MP3, movies, etc.) playback time. The loudspeaker’s ALC provides designers with several options to control audio distor...
ZMDI introduces new member of its cost-effective high-voltage line driver family for factory automation with IO-Link functionality
ZMDI today announced a new member of its cost-effective line driver and level shifter IC family with a high-voltage I/O channel that meets the physical layer requirements of sensor and actuator systems used in factory automation applications. An integrated DC/DC converter allows power supply of external sensor and actuators with up to 15V, saves board space and design costs. The ZIOL2201 is function- and pin-compatible with the ZIOL2401 and ZIOL...
Analog Devices Introduces Integrated Analogue Front-End Subsystem for Diagnostic-Quality ECG Applications
An ECG (electrocardiogram) system measures and records the electrical activity of a human heart in exceptional detail, enabling accurate analysis of numerous heart conditions, including birth defects, arrhythmias, problems with heart valves and lack of blood flow to the heart muscle. Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal-processing applications and long-time supplier to the medical equipment ind...
Vishay - Military Analog Switches and Multiplexers With Hi-Rel DG408 8-Channel Mux
Vishay announced that it has expanded its family of MIL-PRF-38535-screened analog switches and multiplexers with the release of the hi-rel DG408, an 8-channel, single-ended analog multiplexer. In June 2010 the Vishay Siliconix facility in Santa Clara, Calif., was re-qualified by DSCC to manufacture analog switches and multiplexers with screening to MIL-PRF-38535. The MIL-PRF-38535 specification is a standard that establishes the performance, qu...
Semtech Adds World’s Most Sensitive Proximity Function to Capacitive Touchbutton Platform
Semtech has expanded its ultra-low power capacitive touch sensor ICs with a new platform of enhanced proximity sensing devices. The new SX863x capacitive touch button controllers come in 8- and 12-channel versions and feature a long range of proximity detection of 10cm (view SX863x proximity detection range video clip), allowing the sensor to control power-management and other convenience features such as system wake-up, LED wake-up and automati...
Semtech - Single-Cell AA/AAA, 555-Like Analog Timer with Battery-Safe Operation
Semtech announced a sub-1 V analog timer platform that revolutionizes the conventional 555 timer for low-voltage, battery-operated small appliances. The new SX8122 analog timer offers the best-in-class battery life via its intrinsic 0.9 V operation, without the need for an external boost converter and inductor, saving board space and cost. It also adds low-voltage features to the legacy 555 timer, with one output that controls a DC motor or anoth...
NXP Passes Another Milestone in its High Performance Mixed Signal Strategy
NXP Semiconductors and Dover Corporation (NYSE: DOV) today announced that they have signed a definitive agreement whereby Dover’s affiliate Knowles Electronics will acquire NXP’s Sound Solutions business, the leading provider of speaker and receiver components for the mobile handset market. The sale of the Sound Solutions business, which for reporting purposes is included in NXP’s Standard Products segment, will significantly strengthen NX...
Industry’s smallest 2-channel ADC saves space and power
Maxim Integrated Products introduces the MAX11645, the industry’s smallest 2-channel ADC. This 12-bit I2C ADC includes an internal reference in a tiny 1.9mm x 2.2mm wafer-level package (WLP). A 4 x 3 bump array with 0.5mm pitch facilitates layout on four-layer PCBs, while a slim 0.64mm height makes it perfect for designs laying components out on both sides of the PCB. This ADC minimizes both external component count and total solution size, onl...
New PMR Audio Processor Delivers Unrivalled Performance
CML Microcircuits has announced the addition of a new Audio Scrambler and Sub-audio Signalling Processor, the CMX148, to its family of analogue two way radio ICs. This device is intended for use in general leisure and professional PMR terminals in a worldwide market.
ADC drivers boost bandwidth by eliminating parasitics
Maxim Integrated Products introduces the MAX9626–MAX9628, low-noise, low-distortion, 1.1GHz differential amplifiers for driving high-speed pipeline ADCs. These devices integrate gain resistors, thereby eliminating the need for external feedback resistors. This reduces parasitics to enable higher bandwidths and improved THD performance while saving space and cost. The MAX9626–MAX9628 are ideal for driving 12- to 16-bit pipeline ADCs in communi...
