Akustica, which makes its mark building acoustic system-on-chip
solutions, has recently introduced what it calls the "world's first HD microphone that enables HD voice quality in laptop PCs and other broadband mobile devices." The firm's AKU2103 is a digital-output microphone
with a "guaranteed wideband frequency response," which means that you can sleep easy knowing that your built-in mic complies with the TIA-920 audio performance requirement for wideband transmission. This MEMS
device crams the mechanical transducer, output amplifier, and sigma-delta converter onto a single chip of silicon, and touts near-immunity to RF and electromagnetic interference as well as to power supply modulation. The surface-mountable unit measures in at just four- x four-millimeters in size, and while pricing details aren't available to the masses just yet, Akustica plans on sampling the AKU2103 in Q3 of this year.
