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,

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

range is within 300mV of ground. Upper input voltage range

reaches 4.2V, and output voltage range reaches 3.8V with a
