2 EVM Setup and Operation
This section includes the setup and operation of the EVM for parameter performance evaluation. Typical
output waveforms are included
2.1 Overview
The basic setup in Figure 10 has the two power supplies required to evaluate isolator performance with
any combination of 3.3
V or 5
V on either side. If both sides are to be evaluated at the same supply voltage, only one power supply is
required and can be used to power both sides of the EVM.
CAUTION
Note that this EVM is for operating parameter performance evaluation only and
not designed for isolation voltage testing. Any voltage applied above the 5.5-V
maximum recommended operating voltage of the isolators will damage the
EVM.
