The AS1001 operates from a nominal 1.5V power supply and delivers 100W peak power output. The amplifier is so efficient that battery-powered amplified loudspeakers can run for up to 10 months on a set of four ‘C’ batteries, playing for three hours per day, vastly reducing CO2 from power generation and pollution from battery production. The amplifier also enables the development of smaller, cooler, mains-powered audio equipment, with fewer heat sinks. Applications include totally wireless speakers, home theatre surround sound speakers and battery-powered travel speakers. Future Audium ICs will support MP3 docking stations and USB powered speakers. The AS1001 architecture uses patented techniques to minimise both fixed power losses and output-dependant variable power losses. The modulation scheme uses low switching rates to minimise switching losses. Power rail switching means that the amplifier operates efficiently from a low voltage rail most of the time, with a DC-DC boost converter driving higher voltage transistors on extreme audio peaks...

The SP16160CH1RB is intermediate frequency (IF) receiver reference design for multi-carrier, multi-standard wireless basestations addressing GSM/EDGE, WCDMA, LTE and WiMAX standards. The subsystem reference design kit gives radio designers the necessary technical material – reference design board, software, schematic, bill of materials (BOM) and Gerber files – to accelerate the design and development of high-performance radio receivers. The SP16160CH1RB reference design board facilitates evaluation of the IF receive signal path performance under a variety of input conditions. When combined with a low-noise, high-linearity RF front-end and sufficient IF filtering, the reference design enables high sensitivity receivers that exceed the stringent multi-carrier GSM requirements in both normal and blocking conditions. The SP16160CH1RB delivers an IF chain receiver sensitivity of -105 dBm, with a 9 dB carrier-to-noise ratio in a 200 kHz channel, at 192 MHz input IF. The SP16160CH1RB operates from a single 5V supply and includes the dual-channel ADC16DV160 16-bit, 160 mega-samples per second (MSPS) pipeline ADC, dual-channel LMH6517 DVGA, and LMK04031B clock jitter cleaner...

The TPS2500 and TPS2501 incorporate a boost switching regulator with an onboard current-limiting switch that saves space and cost by providing an integrated solution that meets 5-V USB power requirements from a 1.8 - 5.25V input. The output current limit can be programmed via an external resistor from as low as 130 mA to as high as 1400 mA, supporting up to two USB ports from a single device. The TPS2500 features a pulse-skipping mode for high efficiency at light loads, while the TPS2501 employs fixed-frequency operation across the load range for EMI sensitive designs. Both devices are designed for battery powered portable devices, set top boxes, printers or any USB application without native 5V supply...

34nm NAND technology is the result of continual improvements and innovations over the last several years and has been in mass production since the fall of 2008. It is the smallest NAND production node in the world, keeping Micron well ahead of competitors, and has been the foundation for several key products over the last year:
