Disable Function
The EL2227C is in the standard dual amplifier package
without the enable/disable function. A simple way to
implement the enable/disable function is depicted
below. When disabled, both the positive and negative
supply voltages are disconnected (see Figure 2 below.)
Power Dissipation
With the wide power supply range and large output drive
capability of the EL2227C, it is possible to exceed the
150°C maximum junction temperatures under certain
load and power-supply conditions. It is therefore impor-
tant to calculate the maximum junction temperature
(TJMAX) for all applications to determine if power sup-
ply voltages, load conditions, or package type need to be
modified for the EL2227C to remain in the safe operat-
ing area. These parameters are related as follows:
where:
PDMAXTOTAL is the sum of the maximum power dissi-
pation of each amplifier in the package (PDMAX)
PDMAX for each amplifier can be calculated as follows:
where:
TMAX =Maximum Ambient Temperature
θJA =Thermal Resistance of the Package
PDMAX =Maximum Power Dissipation of 1 Amplifier
VS =Supply Voltage
IMAX =Maximum Supply Current of 1 Amplifier
VOUTMAX=Maximum Output Voltage Swing of the
Application
RL =Load Resistance
To serve as a guide for the user, we can calculate maxi-
mum allowable supply voltages for the example of the
video cable-driver below since we know that TJMAX =
150°C, TMAX = 75°C, ISMAX = 9.5mA, and the package
θJAs are shown in Table 1. If we assume (for this exam-
ple) that we are driving a back-terminated video cable,
then the maximum average value (over duty-cycle) of
VOUTMAX is 1.4V, and RL = 150, giving the results
seen in Table 1.
Single-Supply Operation
The EL2227C have been designed to have a wide input
and output voltage range. This design also makes the
EL2227C an excellent choice for single-supply opera-
tion. Using a single positive supply, the lower input
voltage range is within 200mV of ground (RL = 500),
and the lower output voltage range is within 875mV of
ground. Upper input voltage range reaches 3.6V, and
output voltage range reaches 3.8V with a 5V supply and
RL = 500. This results in a 2.625V output swing on a
single 5V supply. This wide output voltage range also
allows single-supply operation with a supply voltage as
high as 28V.
Gain-Bandwidth Product and the -3dB
Bandwidth
The EL2227C have a gain-bandwidth product of
137MHz while using only 5mA of supply current per
amplifier. For gains greater than 2, their closed-loop ----
-3dB bandwidth is approximately equal to the gain-
