Additional Notes
When probing the MAX747 circuit, avoid shorting AV+
to GND (the two pins are adjacent to each other) as
this may cause the IC to malfunction due to large
ground currents. Also, the MAX747 may continue to
operate with AV+ disconnected, but erratic switching
waveforms will appear at EXT. Finally, due to its fast
switching and high drive capability requirements, EXT
is a low-impedance point that is not short-circuit
protected. Therefore, do not short EXT to any node
(including AGND and V+, which are adjacent to EXT)
to prevent damaging the device.
