Figure1. A2327 test set up circuit
Figure2. 30 kHz LPF for A2327 test
NOTE1: CS should be placed as close as possible to VDD/GND pad of the device
NOTE2: CI should be shorted for any Common-Mode input voltage measurement
NOTE3: A 33uH inductor should be used in series with RL for efficiency measurement
NOTE4: The 30kHz LPF (shown in figure 1) is required even if the analyzer has an internal LPF
