Promising significantly longer playback time in portables,
the WM8912 d/a converter (DAC) exploits a unique low power DAC capacitor
switching architecture that enables a DAC to headphone power consumption
of less than 4 mW. It also employs proprietary Class W amplifier
technology with an adaptive dual drive charge pump and dc-servo-circuit
architecture. Other features include a control write sequencer, flexible
clocking options, and a programmable dynamic range controller. Available
in a 32-pin, 4 mm x 4 mm QFN, price is $1.52 each/1,000. WOLFSON
MICROELECTRONICS PLC, San Diego, CA. (858) 676-5090.

The AUIRF7739L2 and AUIRF7665S2 automotive DirectFET 2 power
MOSFETs report exceptional power density and feature dual-sided cooling,
low parasitic inductance and resistance, and a robust, reliable, and
AEC-Q101 qualified package. The AUIRF7739L2 claims to exhibit the
industry’s lowest on resistance at 0.7 mΩ typical at 40V. Housed in
a large can, it features a 60% smaller footprint and 85% lower profile
than a D2PAK. Reportedly, the AUIRF7665S2 small can device is optimized
for a very low gate charge and exhibits extremely low parasitics. Both
devices are qualified according to AEC-Q101 standards and offer an
environmentally-friendly, lead-free, and RoHS-compliant BOM. Pricing for
the AUIRF7739L2 and the AUIRF7665S2 begins at $2.60 and $0.46 each,
respectively, in low volume quantities. For more information, contact
Sian Cummins at INTERNATIONAL RECTIFIER, El Segundo, CA. (310) 252-7148.

Expanding the company’s portfolio of high-temperature
components are single- and dual-row 2.54-mm contact centerline male
headers and dual-row card edge connectors available in 1-mm, 1.27-mm,
2.54-mm, 3.18-mm, and 3.96-mm contact centerline versions. The
connectors are capable of reliable operation in temperatures ranging
from -65°C to +250°C. Available mounting styles include clearance
holes, flush mounting, threaded inserts, straddle mount, floating
bobbin, side mounting, and open card slot. The headers are available
with varied head and tail length options for custom and standard
applications. Both the card-edge connectors and headers specify a
current rating from 1A to 3A maximum per contact. Prices start at $0.12
each/1,000 for two-position/four-pin single-row headers and $1.70
each/1,000 for four-position/eight-pin dual-row card edge connectors.

Available in multiple wavelengths, the QuasarBrite family of
UV LEDs promise a 10-times longer lifespan, enhanced durability, and up
to 50% cost savings when compared to similar devices. The through-hole
LEDs are available in wavelengths of 385 nm, 405 nm, and 415 nm at 4 mW
to 6 mW. In addition to enhanced life span, they feature a uniform beam
pattern and up to 70% lower energy consumption than CCFLs. Pricing,
depending on size and quantity, is approximately $2.50 to $5.25 each in
production quantities. LUMEX INC., Palatine, IL. (800) 278-5666.

Enhancing the Prodigy motion-control card family are
additional features and peripherals that promise to simplify programming
and connectivity. All Prodigy/CME controllers now include user
accessible on-board non-volatile random-access memory (NVRAM). The
upgrade to NVRAM allows users to store configuration parameters, program
variables, and other data directly on the card rather than loading them
during power up. Adding to the facelift, the IM-600 interconnect module
eases interfacing motion peripherals to the Prodigy card. The module
connects to the Prodigy’s option connector and pulse-and-direction
connector, thereby providing jack screw breakout functionality. Also,
the IM-600 features a DIN mountable package for easy panel mounting.

Ixia, a provider of converged IP-performance test systems, in
partnership with Agilent Technologies unveils what it’s calling “the
world's first solution for HDMI Ethernet Channel networking test”.
Essentially, the instrument combines Ixia's IxN2X traffic generator with
Agilent's HDMI Ethernet channel and audio return channel physical layer
test solution, making it the first to offer a complete solution for
testing devices according to the HDMI 1.4 compliance test specification,
supplement 2. Protocol testing of devices using the HDMI Ethernet
channel is made possible with the IxN2X Test Solution used in
conjunction with Ixia’s N5610A HDMI-Ethernet converter. For more
details, call IXIA, Santa Clara, CA. (877) 367-4942.
