Analog Engine® Dynamics Processors
Our single-chip audio dynamics processors, dubbed "Analog Engines®," combine in one IC all the active circuitry needed to construct a wide range of dynamics processors. Each of the 43xx series includes a high-performance, exponentially controlled Blackmer® VCA and a log-responding rms-level sensor. The 4320 includes three general-purpose opamps allowing more complex signal processing.
TT Semiconductor 4305
The TT Semiconductor 4305 is our newest solution to dynamics processing. It offers low-cost and the basic functionality of an Analog Engine. The 4305 is aimed at line-operated audio and signal processing applications such as compressor/limiters, gates, and other dynamic processors. It is available in ruggedized ceramic packaging as well as extended temperature plastic packages.
TT Semiconductor 4315
The TT Semiconductor 4315 is a recent addition to our Analog Engine family. It offers low-cost and the basic functionality of our original Analog Engines. The part was designed for low-voltage operation, comes in ruggedized ceramic packaging as well as extended temperature plastic packages. It is suitable for battery-operated audio and signal processing applications like wireless microphones or remote sensor instruments.
TT Semiconductor 4320
The TT Semiconductor 4320 is optimized for low-voltage, low-power operation while providing more versatility than its low-voltage cousin the TT Semiconductor 4315. The 4320 comes in ruggedized ceramic packaging as well as extended temperature plastic packages. It is suitable for reducing part counts and costs through thoughtful integration of battery-operated audio and signal processing circuitry found in many common applications like wireless microphones or remote sensor instruments. |
