An ammeter is always connected in series with the component whose current you want to measure. This means it is placed ...

Fig 1. Two multiplexers (U2 and U3) enable this data-acquisition IC (U1) to monitor up to 12 battery temperatures in a configuration that saves power when it isn’t actively making measurements. Fig 2.

This is probably fairly straightforward for an EE to weigh in on so I thought I’d post this question here for posterity in the hopes that it’ll solve the issue for other designers. The challenge is ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...
