EL2045
Data Sheet February 11, 2005 FN7030.1
Low-Power 100MHz Gain-of-2 Stable Features
Operational Amplifier
100MHz gain-bandwidth at gain-of-2
The EL2045 is a high speed, low power, low cost monolithic
Gain-of-2 stable
operational amplifier built on Elantec's proprietary
Low supply current - 5.2mA at V = 15V
complementary bipolar process. The EL2045 is gain-of-2
S
stable and features a 275V/s slew rate and 100MHz gain-
Wide supply range - 2V to 18V dual-supply and 2.5V to
bandwidth at gain-of-2 while requiring only 5.2mA of supply
36V single-supply
current.
High slew rate - 275V/s
The power supply operating range of the EL2045 is from
Fast-settling - 80ns to 0.1% for a 10V step
18V down to as little as 2V. For single-supply operation,
the EL2045 operates from 36V down to as little as 2.5V. The Low differential gain - 0.02% at A =+2, R = 150
V L
excellent power supply operating range of the EL2045

makes it an obvious choice for applications on a single +5V
Wide output voltage swing - 13.6V with V = 15V,
or +3V supply. S
R =1k and 3.8V/0.3V with V =+5V, R =500

The EL2045 also features an extremely wide output voltage
Pb-Free available (RoHS compliant)
swing of 13.6V with V = 15V and R = 1k. At 5V,
S L
output voltage swing is a wide 3.8V with R = 500 and

Applications
3.2V with R = 150. Furthermore, for single-supply
L
operation at +5V, output voltage swing is an excellent 0.3V to Video amplifiers
3.8V with R = 500.

Single-supply amplifiers
At a gain of +2, the EL2045 has a -3dB bandwidth of
Active filters/integrators
100MHz with a phase margin of 50. Because of its
High speed sample-and-hold
conventional voltage-feedback topology, the EL2045 allows
the use of reactive or non-linear elements in its feedback
High speed signal processing
network. This versatility combined with low cost and 75mA of
ADC/DAC buffers
output-current drive makes the EL2045 an ideal choice for
price-sensitive applications requiring low power and high Pulse/RF amplifiers
speed.

NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
V- 4 5 NC
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.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
