EL2045 pdf datasheet (Low-Powe

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 gainbandwidth
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 VS = ±15V and RL = 1kΩ. At ±5V,
output voltage swing is a wide ±3.8V with RL = 500Ω and
±3.2V with RL = 150Ω. Furthermore, for single-supply
operation at +5V, output voltage swing is an excellent 0.3V to
3.8V with RL = 500Ω.
