THAT Corp. 1583 Low Noise Audio Preamp IC

THAT 1583 Low Noise Audio Preamp IC is a versatile, high performance current-feedback amplifier suitable for differential microphone preamplifier and bus summing applications. It improves on previous, traditional current feedback designs by offering a more versatile configuration that can yield lower noise at low gains, lower distortion overall, and higher slew rate. Amplifier gain is determined by three external resistors. This makes it possible to optimize noise and bandwidth over a wide range of gains, as well as optimize the taper of gain vs. rotation in variable-gain, pot-controlled applications. The 1583 is designed to mate perfectly with THAT's series of Digital Preamplifier Controller ICs to produce an optimized, digitally controlled preamplifier. The 1583 operates from as little as 5V up through 18V supplies. It accepts greater than +28dBu input signals at unity gain when operated from 18V supplies.

THAT Corp. 1583 Demonstration Board

THAT 1583-DEMO Digitally Controlled Mic Preamp Demo Board allows developers to evaluate the THAT1583 digital gain controller IC with any member of the growing family of THAT differential output microphone preamplifiers. A fully featured microphone preamplifier is demonstrated with phantom power switching and fault protection, mic/line switching. RFI filtering, and output conditioning. The board is controlled by a user-friendly PC graphical user interface over USB.

  • Demonstrates a complete digitally controlled microphone preamplifier circuit based on THAT5173 IC
  • Controls gain of the 1570 or 1583 microphone preamplifier
  • Balanced audio input/output on XLR and TRS connectors
  • Supports pro audio signal levels: +23dBu (input and output, ±15V supplies)
  • Gain adjustable in 3dB steps from 0dB to 60dB
  • Easy to use PC Graphical User Interface software
  • Generous prototyping area
