Gain-Bandwidth Product and the -3dB Bandwidth
The EL1516 has a gain-bandwidth product of 300MHz while
using only 6mA of supply current per amplifier. For gains
greater than 2, their closed-loop -3dB bandwidth is
approximately equal to the gain-bandwidth product divided
by the noise gain of the circuit. For gains less than 2, higher-
order poles in the amplifiers' transfer function contribute to
even higher closed loop bandwidths. For example, the
EL1516 has a -3dB bandwidth of 350MHz at a gain of +2,
dropping to 80MHz at a gain of +5. It is important to note that
the EL1516 has been designed so that this “extra” bandwidth
in low-gain applications does not come at the expense of
stability. As seen in the typical performance curves, the
EL1516 in a gain of +2 only exhibits 0.5dB of peaking with a
1000
Ω load.
Output Drive Capability
The EL1516 has been designed to drive low impedance
loads. It can easily drive 6VPP into a 100Ω load. This high
output drive capability makes the EL1516 an ideal choice for
RF, IF and video applications.
Printed-Circuit Layout
The EL1516 is well behaved, and easy to apply in most
applications. However, a few simple techniques will help
assure rapid, high quality results. As with any high-frequency
device, good PCB layout is necessary for optimum
performance. Ground-plane construction is highly
recommended, as is good power supply bypassing. A 0.1F
ceramic capacitor is recommended for bypassing both
supplies. Lead lengths should be as short as possible, and
bypass capacitors should be as close to the device pins as
possible. For good AC performance, parasitic capacitances
should be kept to a minimum at both inputs and at the
output. Resistor values should be kept under 5k
Ω because
of the RC time constants associated with the parasitic
capacitance. Metal-film and carbon resistors are both
acceptable, use of wire-wound resistors is not recommended
because of their parasitic inductance. Similarly, capacitors
should be low-inductance for best performance.
