Fast data aquisition 2


Posted on Jun 1, 2012

a low cost, high-speed monolithic analog multiplexer. The system works as follows: Selects a channel and initiates a conversion at G = 1 and then looks at the MSB of the conversion result. If the MSB = 1, the ?? will store the value. If the MSB = 0, the ?? will select G = 2. The ?? will repeat the cycle of gain incrementing, comparison, and analog-to-digital conversion until the MSB = 1.

The ?? will then test for an output of all l's, as this is the full-scale output of the A/D. If the output is all l's, the ?? will decrement the gain by 1 step and perform the final conversion.
