LM308N

The LM308N is one member of the LM308 family,it is designed as one kind of operational amplifiers which having specifications a factor of ten better than FET amplifiers over -b55 to +125 temperature range.It is guaranteed from b55§C to a125§C, the LM208 from -25 to +85, and the LM308 from 0 to +70.The low current error of the LM308 series makes possible many designs that are not practical with conventional amplifiers.In fact, it operates from 10 MX source resistances,introducing less error than devices like the 709 with 10 kX sources.Integrators with drifts less than 500 mV/sec and analog time delays in excess of one hour can be made using capacitors no larger than 1 mF.

Features of the LM308N are:(1)offset current less than 400 pA over temperature;(2)supply current of only 300 mA, even in saturation;(3)guaranteed drift characteristics;(4)maximum input bias current of 3.0 nA over temperature.And the absolute maximum ratings of the LM308N can be summarized as:(1)supply voltage:+/-18V;(2)power dissipation:500 mW;(3)differential input current:+/-10 mA;(4)input voltage:+/-15V;(5)output short-circuit duration:continuous;(6)operating temperature range:0 to +70;(7)storage temperature range:-65 to +150;(8)lead temperature (soldering,10 sec):260;(9)H package lead temp (soldering 10 seconds):300.If you want to know more information such as the electrical characteristics about the LM308N,please download the datasheet in www.seekdatasheet.com or www.chinaicmart.com.
