General Description
The EL2044C is a high speed, low power, low cost monolithic opera-
tional amplifier built on Elantec's proprietary complementary bipolar
process. The EL2044C is unity-gain stable and features a 325V/µs
slew rate and 120MHz gain-bandwidth product while requiring only
5.2 mA of supply current.
The power supply operating range of the EL2044C is from ±18V
down to as little as ±2V. For single-supply operation, the EL2044C
operates from 36V down to as little as 2.5V. The excellent power sup-
ply operating range of the EL2044C makes it an obvious choice for
applications on a single +5V supply.
The EL2044C also features an extremely wide output voltage swing of
±13.6V with VS = ±15V and RL = 1000. At ±5V, output voltage
swing is a wide ±3.8V with RL = 500and ±3.2V with RL = 150.
Furthermore, for single-supply operation at +5V, output voltage swing
is an excellent 0.3V to 3.8V with RL = 500.
At a gain of +1, the EL2044C has a -3dB bandwidth of 120MHz with
a phase margin of 50°. It can drive unlimited load capacitance, and
because of its conventional voltage-feedback topology, the EL2044C
allows the use of reactive or non-linear elements in its feedback net-
work. This versatility combined with low cost and 75mA of output-
current drive makes the EL2044C an ideal choice for price-sensitive
applications requiring low power and high speed.
