High Performance Digital Mic Pre Now Shipping!

THAT Corp's 2-chip set offers outstanding analogue preamp with digital gain control

This is the product you've been waiting for! THAT Corporation's no-compromise solution of THAT1570 Low Noise Audio Preamplifier and THAT5171 Digital Preamp Controller is now available and ready for your next-generation products. The chip set's analogue specifications and sonic qualities are superb (like 1nV/rtHz noise at 60dB gain, 4.2MHz bandwidth, THD+N of 0.0008% at 40dB gain, and slew rate of 53V/µs). Digital gain control is via an addressable serial-peripheral interface (SPI), with gain programmable at 5.6dB, and from 13.6 to 68.6dB in 1dB steps.

The THAT1570/5171combination spec out at 1nV/rtHz noise at 60dB gain, with a bandwidth of 4.2MHz and THD+N of 0.0008% (40dB gain), and a 53V/us slew rate. Digital control is via an addressable serial-peripheral interface (SPI) and gain is programmable at 5.6dB, and from 13.6 to 68.6dB in 1dB steps.

THAT's engineers pulled out all the stops to ensure the THAT1570/5171combination will be suitable for even the most demanding applications. They've provided a differential servo which reduces output offsets to less than 1mV, and patent-pending techniques to minimize zipper noise. The differential audio signal output, 4 general purpose digital outputs, and versatile SPI bus combine to simplify design without limiting flexibility and creativity.

Now there's a digitally controlled mic pre you can trust to deliver the goods, don't wait to get your hands on this outstanding chip set. Samples, demo boards, and production quantities are available now by contacting any Profusion sales office.

Simplified Solutions for Digital Wireless Audio

Mini Boards Provide Fully Functional Links

New from Resolute Audio, the RA-W series Wireless Link Boards are a quick, low-cost way to evaluate SYNIC™ wireless technology, or to incorporate it directly into a wide range of diverse applications. SYNIC™ technology combines a number of advanced techniques — including spread spectrum and frequency hopping — to stream high quality digital audio with a high degree of tolerance to interference in the 2.4GHz band.

Configured using one of a variety of plug-in modules to meet your specific design requirements, the RA-WTX (transmitter) and RA-WRX (receiver) need only power supplies to enable full functionality and immediate use with no further user adjustment, saving both time and cost.
