APPLICATIO S I FOR ATIO
WUUU
In some applications, a long cable or wire is used to connect
the LT3482 to APD. When APD is shorted to GND, APD pin
voltage might ring below ground and damage the internal
circuitry. To prevent damage during short-circuit event, a
20Ω resistor must be added in series with the APD.
Layout Hints
The high speed operation of the LT3842 demands care-
ful attention to board layout. You will not get advertised
performance with careless layout. Figure 3 shows the
recommended component placement.
