EL4093C
300 MHz DC-Restored Video Amplifier
Applications Information
Contd
If the video does not contain any AC components
during the autozero level (eg RGB video) then
the above networks are not needed and the CFA
output can be connected directly to the SH in-
put
Power Dissipation
The EL4093 current feedback amplifier has an
absolute maximum of g30 mA output current
drive This is slightly more than the current re-
quired to drive g2V into 75
X To see how much
the junction temperature is raised in this worst
case we refer to the equations below
TJMAX e TMAX a (iJA PDMAX)
where
TMAX
e
Maximum Ambient Temperature
iJA
e
Thermal Resistance of the Package
PDMAX e Maximum Power Dissipation of the
CFA and SH amplifier in the Pack-
age
PDMAX for either the CFA or the SH amplifier
can be calculated as follows
PDMAX e (2 VS ISMAX)

Load Resistance
For the EL4093 the maximum supply current is
115 mA on VS e g5V Assume that in the worst
case the CFA output swings g2V into 75
X
Since the SH has a current output we assume
that it is at maximum current swing (g55 mA)
but at a mid-rail output voltage (0V) With the
above assumptions PDMAX for the EL4093 is
223 mW and using the thermal resistance of a
narrow SO package (120 CW) this yields a tem-
perature increase of 27 C Since the maximum
ambient temperature is 85 C the resulting junc-
tion temperature of 112 C is still below the maxi-
mum
Please note that there is no short-circuit protec-
tion on the EL4093 CFA output and hence the
minimum short circuit current (60 mA) is greater
than the absolute maximum output current
Maintaining the EL4093 in this state for more
than a few seconds may cause the part to exceed
TJMAX in addition to metal migration problems
