Ordering Information
NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with
both SnPb and Pb-free soldering operations. Intersil Pb-free products
are MSL classified at Pb-free peak reflow temperatures that meet or
exceed the Pb-free requirements of IPC/JEDEC J STD-020.
Low-Power 100MHz Gain-of-2 Stable
Operational Amplifier
The EL2045 is a high speed, low power, low cost monolithic
operational amplifier built on Elantec's proprietary
complementary bipolar process. The EL2045 is gain-of-2
stable and features a 275V/µs slew rate and 100MHz gain-
bandwidth at gain-of-2 while requiring only 5.2mA of supply
current.
The power supply operating range of the EL2045 is from
±18V down to as little as ±2V. For single-supply operation,
the EL2045 operates from 36V down to as little as 2.5V. The
excellent power supply operating range of the EL2045
makes it an obvious choice for applications on a single +5V
or +3V supply.
The EL2045 also features an extremely wide output voltage
swing of ±13.6V with V
output voltage swing is a wide ±3.8V with R
±3.2V with R
operation at +5V, output voltage swing is an excellent 0.3V to
3.8V with R
At a gain of +2, the EL2045 has a -3dB bandwidth of
100MHz with a phase margin of 50°. Because of its
conventional voltage-feedback topology, the EL2045 allows
the use of reactive or non-linear elements in its feedback
network. This versatility combined with low cost and 75mA of
output-current drive makes the EL2045 an ideal choice for
price-sensitive applications requiring low power and high
speed.
