description
These devices consist of four independent, high-
gain frequency-compensated Norton operational
amplifiers that were designed specifically to
operate from a single supply over a wide range of
voltages. Operation from split supplies is also
possible. The low supply current drain is
essentially independent of the magnitude of the
supply voltage. These devices provide wide band-
width and large output voltage swing.
The LM2900 is characterized for operation from
–40°C to 85°C, and the LM3900 is characterized
for operation from 0°C to 70°C.

邑人2013-07-31纯英文的文档，没看懂，没用到，貌似是一个芯片的手册
MrAstonMartin2015-09-10英文档 也是够了
