Design Guide for Substituting the THAT2162 for the ADI SSM2164
filler
Analog Devices has discontinued their SSM2164 quad VCA. Our THAT2162 dual VCA is an alternative worth considering. Some of the issues which you'll need to consider are addressed on our
THAT Alternatives to the SSM2164 page.

2162 basic application circuit

DESCRIPTION

The THAT 2162 contains two high-performance Blackmer® voltage-controlled amplifiers (VCAs). With two opposing-polarity, voltage-sensitive control ports, they offer wide-range exponential control of gain and attenuation with low signal distortion. Both VCAs are trimmed at wafer stage to deliver low distortion and control-voltage feedthrough without further adjustment. However, external symmetry adjustment is possible to further optimize distortion and control feedthrough for critical applications.

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.
