D.Module2.ADDA8M12
2-channel, 12 bit, 8MSPS A/D and D/A Frontend
The D.Module2.ADDA8M12 is an A/D, D/A converter daughter card for the D.Module2 family of DSP Computer Modules. The main application areas are ultrasonic and eddy current analysis, radar processing, and communications. The extremely short conversion time also makes this module ideally suited for control loops requiring minimum latency.
This daughter card is based on two THS12082 converters with programmable 16-level
Fifos. The Fifos simplify interfacing and relax timing constraints. The wide input
bandwidth allows to use the ADDA8M12 in subsampling application like I/F sampling
in communications equippment.
The D/A section uses two DAC7821 converters, followed by an output stage capable
of driving 50Ω loads.
For OEM systems the SMA input and output connectors can be removed and replaced by
2.54mm pitch board-to-board connectors. The support software contains ready-to-use
code examples for DMA-based data acquisition and processing.
