    DESCRIPTION

    The THAT5173 is a digital gain controller for low-noise, analog, differential, current-feedback audio preamplifiers such as the THAT 1580, and 1583. When used in conjunction with an appropriate analog gain block, the 5173 supports digitally control gain from 0dB to 60dB in 3dB steps, while preserving low noise and distortion. It operates from ±5V to ±17V analog supplies, supporting input signal levels as high as +27 dBu (at 0dB gain and ±17V supplies) in combination with the 1580 -- without an input pad. The 5173 includes a differential servo and zero-crossing detector to minimize dc offsets and glitches (zipper noise) during gain adjustments.

    The 5173 is controlled via an industry standard serial-peripheral interface (SPI) port. Four General Purpose Outputs (GPOs) can be controlled via this interface. The GPOs may be used to control auxillary functions such as input selectors, filters, mutes, LEDs, relays, etc.

    The 5173 was designed to mate perfectly with the THAT 1580 or 1583 Differential Audio Preamplifier ICs. Together, the 1580/5173 or 1583/5173 combination provides a high performance solution for digitally-controllable audio preamplifier applications. However, the 5173 may also be used to control a discrete preamplifier.

  • Design Note 140   Input and Output Circuits for THAT Preamplifier ICs (244k)

  • Digitally Controlled Microphone Preamplifier Selector

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


    1580/5173 and 1583/5173 Digitally-Controlled Mic Preamp Demo Boards - These THAT Digitally-Controlled Mic Preamp Demo Boards (US$250) allow developers to evaluate the performance of the THAT5173 IC. 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 5173 chip via USB. A prototyping area is available for adding or modifying circuitry. See the 5173 DEMO Datasheet for more information.


    5173 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.


    5173 Material Data Declaration Sheet

    Material Data Declaration Sheets (MDDS) disclose the hazardous materials in our integrated circuits as required by the European RoHS directive.
