1583X/5263-DEMO

1583X/5263-DEMO is a 2-channel digitally-controlled Mic preamp demonstration board. It allows developers to evaluate the THAT5263 digital gain controller IC with THAT differential output microphone preamplifiers. A fully featured microphone preamplifier is demonstrated with phantom power switching and fault protection, mic/line inputs, RFI filtering, and output conditioning. The board is controlled by a user-friendly PC graphical user interface over USB. The THAT5263-DEMO board demonstrates the 5263 mated with the 1580 and 1583 mic preamplifier ICs in a typical circuit. An easy to use USB Graphical User Interface provides total control over all 5263 features.
