The EL2245 and EL2445 are dual and
quad versions of the popular EL2045.
They are high speed, low power, low
cost monolithic operational amplifiers built on Elantec's
proprietary complementary bipolar process. The EL2245
and EL2445 are gain-of-2 stable and feature a 275V/μs slew
rate and 100MHz bandwidth at gain-of-2 while requiring only
5.2mA of supply current per amplifier.
The power supply operating range of the EL2245 and
EL2445 is from ±18V down to as little as ±2V. For singlesupply
operation, the EL2245 and EL2445 operate from 36V
down to as little as 2.5V. The excellent power supply
operating range of the EL2245 and EL2445 makes them an
obvious choice for applications on a single +5V or +3V
supply.
The EL2245 and EL2445 also feature 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
