10.2 Typical Application

A common feature of many PMUs (precision measurement units) is the ability to change current ranges. This allows for a system defined current clamp when testing devices and reduces possible damage to the PMU and DUT (device under test). In high voltage PMUs, large relays are often used to enable this switching, but this comes with the trade-off of size. To reduce system size, a multi-channel high voltage switch can be added to facilitate this switching with minimal impact to system size and performance. The TMUX821x allows for switching between multiple current ranges, and has the added flexibility to use multiple channels in parallel for high current applications.
