Description
LM308AH Op-amp in an 8 pin TO-5 can by National Semiconductor
General Description
The LM108 series are precision operational amplifiers having specifications a factor of ten better than FET amplifiers
over a -55’C to +125’C temperature range.
The devices operate with supply voltages from +-2V to
+-20V and have sufficient supply rejection to use unregulated supplies. Although the circuit is interchangeable with and
uses the same compensation as the LM101A, an alternate
compensation scheme can be used to make it particularly
insensitive to power supply noise and to make supply bypass capacitors unnecessary.
The low current error of the LM108 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.
The LM108 is guaranteed from b55§C to a125§C, the
LM208 from -25’C to +85’C, and the LM308 from 0’C to
+70’C.

These came to us as part of a lot of surplus stock from a large ‘Milspec’ type Co. and are date coded 8444 we have therefore classified them as ‘new other’
They are stored with us still in original manufacturers packaging are in as new condition and will function perfectly – to their full original specification.
