-- Responding to industry demand for ever higher performance, THAT
Corporation (booth # 2805) has released its advanced microphone preamp
IC, the THAT1512. Boasting
lower noise over a wider range of gain settings than any integrated
circuit preamp on the market, the 1512 offers lower distortion, wider
bandwidth, faster slew rate, and reduced supply current compared to
competitive models.
“The
1512 Mic Preamp IC is extraordinarily quiet at both microphone and
line levels,” remarked Les Tyler, President of THAT Corporation.
“Moreover, its bandwidth is nearly three times wider than that of
other ICs, which results in improved distortion and transparency on a
par with discrete designs. This
lets the 1512 deliver discrete performance in IC form.”
According
to Gary Hebert, THAT's Chief Technology officer, "the THAT1512 is
designed for the exacting requirements of professional audio
equipment. At 60dB gain,
its input noise -- at 1 nV/root-Hertz -- adds only 1.3 dB noise to
that of a 200 Ohm microphone. Yet,
at 0dB gain, the 1512's input noise rises to only 32 nV/root-Hertz --
matching that of most conventional line-input stages."
Hebert added, "this makes the 1512 capable of
no-compromise performance from mic to line levels -- previously
unheard of for an IC preamp."
Tyler
pointed out that the 1512 pin configuration is compatible with several
existing industry-standard ICs whose performance it surpasses, making
it a candidate for drop-in replacement in existing designs as well as
the choice for new development. The
part operates over a wide range of supply voltages – from ±5V to ±20V
– and typically draws only 6 mA of supply current.
Applications
for the new part include input stages and summing amplifiers in mixing
consoles, breakout boxes, portable recording equipment, and other gear
requiring a versatile, high performance microphone preamp stage at a
reasonable cost.
According
to Fred Floru, designer of the 1512, critical listeners are likely to
find the new IC unusually transparent in part thanks to its unique
construction. Floru noted
"the THAT1512 is manufactured using THAT’s proprietary
'dielectric isolation' (DI) process which encapsulates each transistor
in its own insulating well. The
complete electrical isolation provided by the DI process means the
1512 more closely resembles a fully discrete design.
With device interaction reduced to a minimum, we’ve nearly
eliminated the stray interactions that can impinge on the audio signal
and ultimately degrade a microphone preamp’s sound quality.”
The
THAT1512 is available in DIP-8, SO-8, and SO-14 packages, all suitable
for conventional or lead-free soldering processes. A companion part, the 1510, is available in DIP-8, and 300-mil
SO16 packages. Other
packages will be considered upon request.
1k pricing for the 1512 SO-8 version is $2.46, for the 1510
DIP-8 is $2.05. For more specifications of our newest IC visit the 1510/1512

THAT
Corporation, founded in 1989, provides high-performance analog
integrated circuits to the professional audio manufacturer, and is
best known for its line of IC voltage-controlled amplifiers (VCAs) and
RMS-level detectors used throughout the pro audio industry. The
company is headquartered in
Milford,
Massachusetts, with offices in
Tokyo,
Japan
and
Milpitas,
California. In addition to its IC business, THAT also licenses noise reduction
technology to the TV broadcast and reception industries.
