Low Power Precision Op Amp Allows Fast, Accurate Multiplexing
If you need to measure many analog voltages, but not necessarily all at the same time, then a common approach is to multiplex these signals together into one output signal, so that you can then process and digitize each of these original voltage levels one at a time using shared circuitry. But doing this right requires some attention to detail, especially if you want to switch between channels quickly, measure accurately, and do all this at relatively low power consumption. This video discusses key issues to consider when choosing op amps for multiplexed applications. We introduce the unique ways in which the LT6020 op amp addresses those issues.
