Multiplexed Input Signals
Input Sample Time. The IST field allows software to specify the length of the sample
window. Provision is made to vary the input sample time, through software control, to offer
flexibility in the source impedance of the circuitry providing the QADC64E analog channel
inputs. Longer sample times permit more accurate A/D conversions of signals with higher
source impedances. The programmable sample time can also be used to increase the time
interval between conversions to adjust the queue execution time or the sampling rate.
0 QCLK period x 2
1 QCLK period x 8
Channel Number. The CHAN field selects the input channel number. The software
programs the channel field of the CCW with the channel number corresponding to the
analog input signal to be sampled and converted. The analog input signal channel number
assignments and the signal definitions vary depending on whether the multiplexed or
non-multiplexed mode is used by the application. As far as the queue scanning operations
are concerned, there is no distinction between an internally or externally multiplexed
analog input. Refer to
external multiplexing.
