ADS12
4-channel, 12 bit, high-end data acquisition frontend
The ADS12 from Sematec 
is a high-end data acquisition frontend for DSP systems. It offers 4 fully
differential input channels which are sampled synchronously by precision 12-bit
300 KSPS successive approximation A/D converters.
Also provided are 2 single-ended analog outputs, driven by 12-bit D/A convertes.
Key application areas are industrial control systems, measurement, and robotics. The analog inputs are equipped with programmable antialiasing filters and programmable input range. The D/A converters are followed by programmable smoothing filters.
Independent and synchronous sampling of the inputs is supported. Successive approximation converters make the board an ideal choice for servo, control and analysis systems. The D.Module compatible bus interface allows glueless connection to all D.Module DSP Computer Modules.
