Printed Circuit Board Layout Techniques
Proper high speed PCB design rules should be used for all
wideband amplifiers as the PCB parasitics can affect the
overall performance. Most important are stray capacitances
at the output and inverting input nodes as it can effect
peaking and bandwidth. A space (3/16
″ is plenty) should be
left around the signal lines to minimize coupling. Also,
signal lines connecting the feedback and gain resistors
should be short enough so that their associated inductance
does not cause high frequency gain errors. Line lengths less
than 1/4
″ are recommended.
Video Performance
This device designed to provide good performance with
NTSC, PAL, and HDTV video signals. Best performance is
obtained with back terminated loads as performance is
degraded as the load is increased. The back termination
reduces reflections from the transmission line and
effectively masks transmission line and other parasitic
capacitances from the amplifier output stage.
ESD Protection
All device pins have limited ESD protection using internal
diodes to power supplies as specified in the attributes table
(see Figure 22). These diodes provide moderate protection
to input overdrive voltages above the supplies. The ESD
diodes can support high input currents with current limiting
series resistors. Keep these resistor values as low as possible
since high values degrade both noise performance and
frequency response. Under closedloop operation, the ESD
diodes have no effect on circuit performance. However,
under certain conditions the ESD diodes will be evident. If
the device is driven into a slewing condition, the ESD diodes
will clamp large differential voltages until the feedback loop
restores closedloop operation. Also, if the device is
powered down and a large input signal is applied, the ESD
diodes will conduct.
NOTE:
Human Body Model for +IN and –IN pins are
rated at 0.8kV while all other pins are rated at
2.0kV.
