Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
2. Power dissipation must be considered to ensure maximum junction temperature (TJ) is not exceeded.
MAXIMUM POWER DISSIPATION (mW)
MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated is
limited by the associated rise in junction temperature. For
the plastic packages, the maximum safe junction
temperature is 150°C. If the maximum is exceeded
momentarily, proper circuit operation will be restored as
soon as the die temperature is reduced. Leaving the device
in the “overheated’’ condition for an extended period can
result in device damage.

Printed Circuit Board Layout Techniques
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 closed−loop 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 closed−loop 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.
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.
