Product Description
The EL2075 is a wideband monolithic operational amplifier
built on a high-speed complementary bipolar process. The
EL2075 uses a classical voltage-feedback topology which
allows it to be used in a variety of applications requiring a
noise gain
appropriate because of restrictions placed upon the
feedback element used with the amplifier. The conventional
topology of the EL2075 allows, for example, a capacitor to
be placed in the feedback path, making it an excellent choice

EL2075
for applications such as active filters, sample-and-holds, or
integrators. Similarly, because of the ability to use diodes in
the feedback network, the EL2075 is an excellent choice for
applications such as log amplifiers.
The EL2075 also has excellent DC specifications: 200µV,
V
specifications allow the EL2075 to be used in DC-sensitive
applications such as difference amplifiers. Furthermore, the
current noise of the EL2075 is only 3.2pA/ Hz, making it an
excellent choice for high-sensitivity transimpedance amplifier
configurations.
Gain-Bandwidth Product
The EL2075 has a gain-bandwidth product of 2GHz. For
gains greater than 40, its closed-loop -3dB bandwidth is
approximately equal to the gain-bandwidth product divided
by the noise gain of the circuit. For gains less than 40,
higher-order poles in the amplifier's transfer function
contribute to even higher closed loop bandwidths. For
example, the EL2075 has a -3dB bandwidth of 400MHz at a
gain of +10, dropping to 200MHz at a gain of +20. It is
important to note that the EL2075 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 EL2075 in a gain of +10 only
exhibits 1.5dB of peaking with a 100 load.
