近来学习运放，这一颗看起来不错，用的是三极管工艺，不知道CMOS工艺是否也可以实现这样的性能。

General Description
The EL2244C/EL2444C are dual and quad versions of the popular
EL2044C. They are high speed, low power, low cost monolithic oper-
ational amplifiers built on Elantec's proprietary complementary
bipolar process. The EL2244C/EL2444C are unity-gain stable and
feature a 325V/µs slew rate and 120MHz gain-bandwidth product
while requiring only 5.2mA of supply current per amplifier.
The power supply operating range of the EL2244C/EL2444C is from
±18V down to as little as ±2V. For single-supply operation, the
EL2244C/EL2444C operate from 36V down to as little as 2.5V. The
excellent power supply operating range of the EL2244C/EL2444C
makes them an obvious choice for applications on a single +5V or
+3V supply.
The EL2244C/EL2444C also feature an extremely wide output volt-
age swing of ±13.6V with VS = ±15V and RL = 1000W. At ±5V,
output voltage swing is a wide ±3.8V with RL = 500W and ±3.2V with
RL = 150W. Furthermore, for single-supply operation at +5V, output
voltage swing is an excellent 0.3V to 3.8V with RL = 500W.
At a gain of +1, the EL2244C/EL2444C have a -3dB bandwidth of
120MHz with a phase margin of 50°. They can drive unlimited load
capacitance, and because of their conventional voltage-feedback
topology, the EL2244C/EL2444C allow the use of reactive or non-lin-
ear elements in their feedback network. This versatility combined with
low cost and 75mA of output-current drive make the
EL2244C/EL2444C an ideal choice for price-sensitive applications
requiring low power and high speed.
