On the SBC-R9 embedded computer, what is the sampling rate for the analog inputs?

The SBC-R9 has eight analog inputs with an effective bandwidth of 1.23 kHz divided across all eight analog inputs. The A/D device specifies a maximum sampling frequency of 100 kHz and a -3 dB input bandwidth of 1 MHz; however, the analog input sampling rate is determined by the interface time between the processor and the A/D circuit. Therefore, a single analog input can be sampled at a rate of 3.125 ksps with the maximum aggregate sampling rate of 153 samples per second (sps).
