Edge6420
HIGH-PERFORMANCE PRODUCTS – ATE
Application Information
Edge 4707 PPMU
One application for the Edge6420 is to provide necessary
DC voltages and currents for 4 channels of pin electronics
(driver, receiver, load) and per pin measurement units.

•
–2.8 < PPMU (MI) compare high voltage < + 2.8V
–2.8 < PPMU (MI) compare low voltage < + 2.8V
–3.0 < PPMU (FV) < + 14.0V
For example, using the:
• Edge720 Load / Driver / Comparator
• Edge4707 PPMU
with the following specifications:
