- | The two analog input channels of the ADALM1000 (M1k) provide a high input impedance and wide dynamic range which is very helpful for many of the measurements that students would be making around their laboratory activities. However, there are only the two analog inputs. Often, there are many more than two signals in the circuit or system under investigation that the students would like to monitor. Or there could be a number of low bandwidth sensors, such as ambient temperature or light levels around a room, that need to be measured or monitored over a long duration of time when gathering experimental data. Any number of external analog multiplexer integrated circuits could be used to expand the number of voltage input channels. The widely available CD4053 triple 2-Channel analog multiplexer IC can be used can be used for this purpose. The rest of this document provides the connections needed for use with the ALICE desk-top External Analog Mux option (as of May 2021 version release). | + | The two analog input channels of the ADALM1000 (M1k) provide a high input impedance and wide dynamic range which is very helpful for many of the measurements that students would be making around their laboratory activities.
