EL2045

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

= ±15V and R

= 1k

. At ±5V,

output voltage swing is a wide ±3.8V with R

= 500

and

±3.2V with R

= 150

. Furthermore, for single-supply

operation at +5V, output voltage swing is an excellent 0.3V to
3.8V with R

= 500

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.
