Dual/Quad Low-Power 100MHz Gain-of-2
Stable Op Amp
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 single-
supply 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 = 1k. At ±5V, output voltage swing is a wide ±3.8V with
RL = 500and ±3.2V with RL = 150. Furthermore, for
single-supply operation at +5V, output voltage swing is an
excellent 0.3V to 3.8V with RL = 500.
At a gain of +2, the EL2245 and EL2445 have a -3dB
bandwidth of 100MHz with a phase margin of 50°. Because
of their conventional voltage-feedback topology, the EL2245
and EL2445 allow the use of reactive or non-linear elements
in their feedback network. This versatility combined with low
cost and 75mA of output-current drive make the EL2245 and
EL2445 an ideal choice for price-sensitive applications
requiring low power and high speed.
