Product Description
The EL2045 is a low-power wideband, gain-of-2 stable
monolithic operational amplifier built on Elantec's proprietary
high-speed complementary bipolar process. The EL2045
uses a classical voltage-feedback topology which allows it to
be used in a variety of applications where current-feedback
amplifiers are not appropriate because of restrictions placed
upon the feedback element used with the amplifier. The
conventional topology of the EL2045 allows, for example, a
capacitor to be placed in the feedback path, making it an
excellent choice for applications such as active filters,
sample-and-holds, or integrators. Similarly, because of the
ability to use diodes in the feedback network, the EL2045 is
an excellent choice for applications such as fast log
amplifiers.
Single-Supply Operation
The EL2045 has been designed to have a wide input and
output voltage range. This design also makes the EL2045 an
excellent choice for single-supply operation. Using a single
positive supply, the lower input voltage range is within
100mV of ground (RL = 500), and the lower output voltage
range is within 300mV of ground. Upper input voltage range
reaches 4.2V, and output voltage range reaches 3.8V with a
5V supply and RL = 500. This results in a 3.5V output
swing on a single 5V supply. This wide output voltage range
also allows single-supply operation with a supply voltage as
high as 36V or as low as 2.5V. On a single 2.5V supply, the
EL2045 still has 1V of output swing.
Gain-Bandwidth Product and the -3dB Bandwidth
The EL2045 has a gain-bandwidth product of 100MHz while
using only 5.2mA of supply current. For gains greater than 4,
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 4, higher-order poles in the
amplifier's transfer function contribute to even higher closed
loop bandwidths. For example, the EL2045 has a -3dB
bandwidth of 100MHz at a gain of +2, dropping to 20MHz at
a gain of +5. It is important to note that the EL2045 has been
