    DESCRIPTION

    The THAT5171 is a digital gain controller for low-noise, analog, differential, current-feedback audio preamplifiers such as the THAT1580. When used in conjunction with an appropriate analog gain block, the 5171 can set gain to 5.6dB, or any gain from 13.6dB to 68.6dB in 1dB steps, while preserving low noise and distortion. It operates from ±5V to ±17V supplies, supporting input signal levels as high as +22 dBu (at 5.6dB gain, and ±17V supplies) in combination with the 1580 (without an external input pad). The 5171 includes a differential servo and zero-crossing detector to minimize dc offsets and glitches (zipper noise) during gain adjustments.

    The 5171 is controlled via an addressable serial-peripheral interface (SPI) port. Four General Purpose Outputs (GPOs) can be controlled via this interface. The GPOs may be connected to input pads, analog switches, mute circuits, LEDs, etc. The SPI bus supports read-back so that host software can verify proper operation.

    The 5171 was designed to mate perfectly with THAT1580 Differential Audio Preamplifier ICs. Together, these ICs provide a best-of-class solution for digitally-controllable audio preamplifier applications. However, for designers who prefer a more customized solution, the 5171 may also be used to control a discrete preamplifier.

  • Digitally Controlled Microphone Preamplifier Selector

    A side by side comparison of the features and specifications of our digitally controlled microphone preamplifier chip sets.


    1580/5171 Digitally-Controlled Mic Preamp Demo Boards - The THAT 1580/5171 Digitally-Controlled Mic Preamp Demo Board (US$250) allows developers to evaluate the performance of the 1580/5171 chipset. The demo board provides a balanced audio input on a Neutrik "combo" connector with 48V phantom power, and a balanced audio output on XLR and ¼" TRS connectors. The supplied graphical user interface (GUI) controls all functions in the 5171 chip via USB. A prototyping area is available for adding or modifying circuitry. See the 1580/5171 DEMO User's Guide for more information.


    5171 Surface Mount Adapter Board - For our integrated circuits which are only available in surface mount packages THAT Corporation offers adapter boards which allow one of these surface-mount ICs to interface to a circuit board via traditional thru-hole mounting. These adapters make it easy for a design engineer to evaluate our surface-mount products on a prototype board without having to employ SMT technology. Adapter boards are available to qualified applicants.
