Intersil has introduced two switches that provide the industry’s optimal solution for eliminating congestion in handheld device connectors. The ISL54214 dual SP3T (Single Pole/Triple Throw) switch or 3:1 Mux combines low distortion audio and two accurate USB 2.0 high speed data (480Mbps) signal switching paths in the same low voltage device. The switches enable use of a common mini USB or audio headphone connector in media players and other po...

A PowerWise stereo headphone amplifier from National Semiconductor draws only 0.9 mA (typical) of quiescent current to double the audio playback time of smart phones, full-featured mobile phones and portable music players.

National Semiconductor has announced it has extended its family of low-power Boomer Class D audio subsystems with two premium quality devices that simplify portable product design. The LM49352 mixed-signal audio subsystem and LM49151 analog subsystem are targeted at smart phones, full-featured phones, portable gaming devices and portable GPS devices.

Users of music phones and MP3 players can benefit from dramatically extended music playback time enabled by two new 25-mW Class-G, DirectPath stereo headphone amplifiers from Texas Instruments, which adjust their voltage supplies to the audio signal to minimize power dissipation. In a standalone Lithium-Ion battery test between TI’s Class-G technology and a competing ground-referenced Class-AB device, the TPA6140A2 and TPA6141A2 reduced pow...

Analog Devices has announced the availability of its latest version of its free, downloadable ADIsimSRD Design Studio for the development of short-range wireless devices. ADIsimSRD Design Studio Version 1.1 conducts real-time simulations, tests configurations and troubleshoots potential problems in short-range radio communications systems using ADI’s ADF70xx family of short-range transmitters and transceivers.

TDC is targeting the growing Internet Appliance market with its smallest-ever embedded WiFi module that provides a plug and play WLAN interface within half the footprint of existing solutions available from TDC. ConnectOne Nano WiReach from TDC can bridge directly from a serial port or wired Ethernet to WiFi, providing a complete implementation including security and networking protocols, firmware, TCP/IP stack and an Internet Controller in a mod...

The Radiometrix RX3G is a PLL based miniature PCB mounted UHF radio data receiver. When used in conjunction with the manufacturer's matching TX3B-869-64 transmitter, it can facilitate the simple implementation of wireless infrastructure that is capable of supporting speeds of 64kbits/s and transmission ranges up to 75m in-building or 300m over open ground.

EAD has introduced a new range of UHF circularly polarised panel antennas designed for RFID applications at 868 MHz. The new range introduces five panel antennas from a very compact panel through to a dual polarised panel antenna.

Texas Instruments has introduced a single-cell battery fuel gauge integrated circuit with Impedance Track technology, which is half the size of its predecessor. The tiny bq27505 stand-alone lithium battery capacity monitoring and reporting device resides in the system and measures only 2.5 x 2 x 0.625 mm, and supports portable applications, such as smart phones, digital cameras and MP3 players, where maintaining long battery life is critical for ...

Texas Instruments has announced that the company will continue to develop and deliver hardware and software solutions for the new standardized ZigBee RF4CE specification for radio frequency (RF)-based remote controls. TI’s portfolio of ZigBee RF4CE system-on-chip products integrates an IEEE 802.15.4-compliant radio, MCU and flash memory, and an extensive set of peripherals. TI is a key contributor to the development of the ZigBee RF4CE version ...
