THAT Corporation 1606/1646-DEMO Demonstration System simplifies evaluating the performance of the 1646 and 1606 OutSmarts Line Driver ICs. The 1606/1646-DEMO comes completely assembled and tested, with both XLR and TRS connectors for line input and output. In addition, a DAC input is supplied on a 3-pin header for easy connection to a digital to analog converter differential output. The DAC input passes the signal through a 50kHz 3rd order low-pass filter that is optionally connected to the 1606 IC.
