The LM108 series are precision operational amplifiers having specifications a factor of ten better than FET amplifiers over -55°C to +125°C temperature range.
The devices operate with supply voltages from ±2V to ±20V and have sufficient supply rejection to use unregulat ed 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 by pass capacitors unnecessary.
Maximum input bias current of 3.0 nA over temperature
Offset current less than 400 pA over temperature
Supply current of only 300mA, even in saturation
Guaranteed drift characteristics
