An InGenius Way to
Eliminate Noise
 Milford,
Ma -- THAT Corporation is auditioning its InGenius®
balanced line receiver ICs at booth 1519 on the AES show floor.
According to the company’s President, Les Tyler, "With
InGenius, design engineers can now build true, real-world interference
rejection into their audio equipment. These ICs incorporate patented
circuitry that significantly improves over the noise- and
interference-canceling ability of other integrated solutions."
THAT’s InGenius IC family is now available in surface mount
and through-hole packages, in three different gain options to suit
specific applications. According to Denise Waterhouse, Sales/Marketing
Manager, all six versions are now available from stock.
THAT’s Chief Technical Officer, Gary Hebert, offered some
details: "Conventional balanced line receivers must be driven by perfectly
matched source impedances in order to effectively reject hum and
interference in audio systems. It’s easy to sustain ideal conditions
in the lab, but in the real world, audio outputs, cables and
connectors are subject to all sorts of imperfections that cause
impedance mismatches. You just don’t get lab conditions at a
concert!"
THAT’s InGenius line receivers use technology developed
and patented by Bill Whitlock, President of Jensen
Transformers. He
explained, "My design is almost completely insensitive to the
source impedance imbalances which overwhelm typical balanced input
stages. InGenius line receivers act like a transformer to
present an extremely high input impedance to common mode (noise)
signals. Even with a 600 ohm source-impedance imbalance, the InGenius
topology delivers 70 dB typical common mode rejection. No other
solid-state input stage can deliver that performance!"
THAT’s Principal Engineer Fred Floru, who designed the InGenius
IC family, noted that the company will demonstrate just how much
difference the InGenius can make. "Come by our booth and put on
headphones to compare traditional balanced inputs with InGenius. Both
Bill and I will be on hand to prove to you that one listen will make
you a believer!"
Interested readers can learn more on Saturday Oct 30th, in session
K (Signal Processing part 1) at approximately noon, when Bill presents
a paper co-authored by Fred Floru. The paper is entitled New
Balanced-Input Integrated Circuit Achieves Very High Dynamic Range in Real-World
Systems.
Audio performance for the THAT 1200-series is uniformly high, with
12V/ms slew rate, 20MHz gain-bandwidth product, and 0.0005% audio-band
THD. Fred Floru noted, "as with our 1240-family, the InGenius®
1200 family is available in three different gains – 0, -3, and -6dB
– to match different customer requirements. The -3dB version is
unique. We believe it represents the optimum tradeoff between noise
and headroom for real-world applications."
The 1200-series are made using THAT’s proprietary dielectric
isolation (DI) process in the company’s Milpitas, California
fabrication facility. Mr. Tyler said that, due to the DI process's
ability to deliver discrete device performance, "these parts
sound like discrete designs, but with the size, reliability, and
convenience of ICs."
Priced at $2.87 (1k) in an 8-pin SO package, the InGenius®
THAT 1200-series is a superior alternative to all other line
receivers. For more information, visit the 1200-series
