Analog Secrets Your Mother Never Told You (1528k)
Originally presented at the 123rd AES Convention, this seminar provides tips and techniques to achieve optimal performance in the analog signal path. Topics covered range from inputs (balanced line and mic level) to outputs (balanced to single-ended), and include analog signal processing (VCAs, RMS detection, and Analog Engines).
2162 Demo Board - The THAT 2162 Demonstration System (US$100) allows the engineer to test the performance of a THAT2162 quickly and easily. The 2162 Demo Board is self-contained circuit board with XLR connectors for signal input and output and a 3-pin header for connection to an external regulated DC power supply (not included). See the 2162 Demo User's Guide for more information.
2162 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.
Harsh Environment Packaging - TT Semiconductor repackages THAT Corporation’s IC products in ruggidized plastic for the medical, aerospace, defense, and heavy industrial marketplaces.
The History of VCAs - THAT Blackmer® VCAs are the successors to the original dbx® line of VCAs. Their development for professional audio use has a long history, and can provide some insight into the care and feeding of these essential devices.
2162 Material Data Declaration Sheet
Material Data Declaration Sheets (MDDS) disclose the hazardous materials in our integrated circuits as required by the European RoHS directive.
