SSM2005 is a 5.1-channel soundfield generator produced by Analog Devices
The SSM2005 is a 5.1-channel soundfield generator that produces true surround sound from any stereo source, including VCD, DVD, and FM broadcasts. It supports both pre-encoded sources like Dolby ProLogic and Circle Surround without requiring external delays or noise reduction processors. The device generates differentiated left and right surround channels for a realistic ambiance effect in 4- or 5-speaker configurations.
The datasheet provides detailed electrical characteristics, including input/output levels, total harmonic distortion, signal-to-noise ratio, and dynamic performance. It includes pin configurations for a 48-lead SSOP package, a simplified block diagram, and typical performance graphs. Licensing information for Circle Surround technology is also included.
