    THAT 1570 Basic Application Circuit

    DESCRIPTION

    The THAT1570 is a versatile, high performance current-feedback amplifier suitable for differential microphone preamp and bus summing applications. The IC comes in a small QFN package, which saves PCB space over discrete and other integrated solutions.

    Gain is adjusted via three external resistors (RA, RB, and RG), making it possible to optimize noise over a wide range of gains. The 1570 supports the traditional approach to gain control (viz., THAT's 1510 or 1512) by fixing RA and RB, and varying RG to control gain. However, the 1570 also supports varying all three resistors simultaneously with a dual-gang potentiometer, or a switched resistor network. This flexible approach enables the designer to optimize noise over a wider range of gains than is possible with fixed RA and RB.

    The 1570 is designed to mate perfectly with THAT's 5171 and 5173 Digital Preamplifier Controller ICs. Along with the 1570, these switched resistor networks provide optimized, digitally controlled audio preamplifiers.

    1570/5171 and 1570/5173 Digitally-Controlled Mic Preamp Demo Boards - A THAT Digitally-Controlled Mic Preamp Demo Board (US$250) allows developers to evaluate the performance of the THAT1570 / THAT5171 or THAT1570 / THAT5173 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 or 5173 chip via USB. A prototyping area is available for adding or modifying circuitry. See the 1570/5171-DEMO Datasheet or the 5173-DEMO Datasheet for more information.


    1570 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.
