Headphone and Speaker Amplifiers

Fairchild Semiconductor (San Jose, CA) has introduced the FAB1200 stereo Class-G ground-referenced headphone amplifier with integrated buck converter, and the FAB2200 audio subsystem with stereo Class-G headphone amplifier and 1.2W Class-D mono speaker amplifier. The FAB1200 features a charge pump that generates a negative supply voltage, allowing the headphone output to be ground-centered and capacitor-free. An integrated inductive buck regulator provides direct battery connection and adjusts the supply voltage between two different levels based on the output signal level resulting in reduced power consumption. The FAB2200 is an audio subsystem that combines a capacitor-free stereo Class-G headphone amplifier with a Class-D speaker amplifier. A proprietary integrated charge pump generates multiple supply rails for a ground-centered Class-G headphone output significantly reducing power dissipation when compared to Class-AB design implementations.

3U VPX Virtex-6 FPGA Processing Board

The Systems division of Elma Electronic Inc. (Fremont, CA) now offers the TIC-FEP-VPX3b, an FPGA-based 3U VPX front-end processing board that provides an FMC site coupled to a large capacity Virtex-6 FPGA for flexible I/O. Featuring an onboard Xilinx Virtex-6 FPGA, the board comes with two banks of 40-bit 1.25 GB DDR3 memory with transfer rates of 7.5 Gbps and a Spartan-6 control node, used to load logic images into the main FPGA. The Spartan-6 control node enables ‘on the fly’ bitstream management for dynamic FPGA configuration. Other resources include zero bus turnaround (ZBT) SRAM with a throughput of 400 MB/sec for expedited read/write processing. Built to the VPX specifications, the TIC-FEP-VPX3b includes four 4-lane fabric ports on the P1, connected by GTX transceivers to the main FPGA. The four fat pipe channels provide the PCIe x4 and GbE interfaces as well as two x4 expansion ports.

Automotive LED Driver ICs

Allegro MicroSystems (Worcester, MA) has announced two new multi-output LED drivers for LCD backlighting. The A8502 and A8514 integrate a current-mode boost converter with internal power switch and multiple current sinks. The LED sinks can be paralleled together to achieve even higher LED currents. They are capable of operating from a single power supply from 5V to 40V, allowing them to withstand a load dump condition encountered in automotive systems. Both the A8502 and A8514 LED drivers can optionally drive an external PMOS to disconnect input supply from the system in the event of a fault. The devices, coupled with the external PMOS disconnect switch, provide protection against output short and overvoltage, open or shorted diode, open or shorted VLED pin, and over-temperature.

Thermal Imager

NEC Avio Infrared Technologies (San Fernando, CA) has introduced its InfReC R300 high-definition thermal imager, which includes thermal movie recording to SD card in radiometric format, thermal/visible integrated images in composite/split-screen display, panoramas, autofocus, and 3.1 MP visible camera. The imager has a resolution (NETD) of 0.05°C and accuracy of ±1°C (1%). The R300 also comes with InfReC Analyzer NS9500PRO PC software, providing realtime recording, data analysis, and report creation. The R300's 320x240 microbolometer detector provides spatial resolution of 1.2 mrad (I.F.O.V) in a spectral range of 8 to 14 microns. The camera's standard temperature measuring range is -40 to 500°C, with an optional high-temperature range of 200 to 2000°C available. The R300 allows simultaneous video capture of thermal/visible images into PC via USB. The range of recording modes includes still visual and IR images, time interval, movies, panoramas, composites, and voice annotation. The detector also has optional lenses: 2x telephoto, 0.5x wide-angle, and close-up.
