The LM108 is a precision operational amplifier 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.
• Maximum Input Bias Current of 3.0 nA over Temperature
• Offset Current less than 400 pA over Temperature
• Supply Current of only 300 μA, even in Saturation
• Ensured Drift Characteristics
