626XDEMO

626XDEMO is a digitally controlled Mic-pre eval board. The board features interchangeable modules for quick and easy performance evaluation and comparison, and all three 626x gain step options. Complete 2-channel low noise programmable-gain preamplifier-ADC driver based on the THAT6261, THAT6263, or THAT6266 ICs. Easy to use PC graphical user interface software provides independent control of gain, enable, mute, ZCD modes, and GPO states. Channels may be linked for “stereo” gain control.

• Balanced microphone-level audio inputs on XLR connectors
• Balanced line inputs with -10dB pad on TRS connectors
• Balanced ADC drive outputs on 3-pin headers
• General-purpose balanced outputs on XLR connectors
• Output filter can be configured to match most popular ADCs
• Runs from bipolar (±5V) or unipolar (+10V) power supplies
• On-board 3.3V regulator for the digital logic supply
• On-board 5 V regulator for the ADC driver supply in unipolar operation
• Switchable phantom power (externally supplied +48V)
• VCM input for external ADC biasing
