less, and disabled when CE is above 4V. Although the logic
levels are not standard TTL, this choice of logic voltages
allows the EL5132 to be enabled by typing CE to ground,
even in 5V single supply applications. The CE pin can be
driving from CMOS outputs.
Supply Voltage Range and Single-Supply
Operation
The EL5132 and EL5133 have been designed to operate
with supply voltages having a span of greater than 5V and
less than 12V. In practical terms, this means that they will
operate on dual supplies ranging from ±2.5V to ±6V. With
single-supply, the EL5132 and EL5133 will operate from 5V
to 12V. To prevent internal circuit latch-up, the slew rate
between the negative and positve supplies must be less
than 1V/s.
As supply voltages continue to decrease, it becomes
necessary to provide input and output voltage ranges that
can get as close as possible to the supply voltages. The
EL5132 and EL5133 have an input range which extends to
within 2V of either supply. So, for example, on ±5V supplies,
the EL5132 and EL5133 have an input range which spans
±3V. The output range of the EL5132 and EL5133 are also
quite large, extending to within 2V of the supply rail. On a
±5V supply, the output is therefore capable of swinging from
-3.1V to +3.1V. Single-supply output range is larger because
of the increased negative swing due to the external pull-
down resistor to ground.
Power Dissipation
With the wide power supply range and large output drive
capability of the EL5132 and EL5133, it is possible to exceed
the 150°C maximum junction temperatures under certain
load and power-supply conditions. It is therefore important to
calculate the maximum junction temperature (TJMAX) for all
applications to determine if power supply voltages, load
conditions, or package type need to be modified for the
EL5132 and EL5133 to remain in the safe operating area.
These parameters are related as follows:
where:
PDMAXTOTAL is the sum of the maximum power
dissipation of each amplifier in the package (PDMAX)
PDMAX for each amplifier can be calculated as follows:
where:
TMAX = Maximum ambient temperature
θ
JA = 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
Power Supply Bypassing And Printed Circuit
Board Layout
As with any high frequency devices, good printed circuit
board layout is essential for optimum performance. Ground
plane construction is highly recommended. Pin lengths
should be kept as short as possible. The power supply pins
must be closely bypassed to reduce the risk of oscillation.
The combination of a 4.7F tantalum capacitor in parallel
with 0.1F ceramic capacitor has been proven to work well
when placed at each supply pin. For single supply operation,
where pin 4 (VS-) is connected to the ground plane, a single
4.7F tantalum capacitor in parallel with a 0.1F ceramic
capacitor across pin 8 (VS+).
For good AC performance, parasitic capacitance should be
kept to a minimum. Ground plane construction again should
be used. Small chip resistors are recommended to minimize
series inductance. Use of sockets should be avoided since
they add parasitic inductance and capacitance which will
result in additional peaking and overshoot.
