Applications Information
Product Description
The EL2044 is a low-power wideband monolithic operational
amplifier built on Elantec's proprietary high-speed
complementary bipolar process. The EL2044 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 EL2044 allows, for example, a
capacitor to be placed in the feedback path, making it an
excellent choice for applications such as active filters,
7
sample-and-holds, or integrators. Similarly, because of the
ability to use diodes in the feedback network, the EL2044 is
an excellent choice for applications such as fast log
amplifiers.
Single-Supply Operation
The EL2044 has been designed to have a wide input and
output voltage range. This design also makes the EL2044 an
excellent choice for single-supply operation. Using a single
positive supply, the lower input voltage range is within
100mV of ground (R
L
= 500Ω), 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
