1 / 13 page OBSOLETE LM108AJAN www.ti.com SNOSAJ6C – FEBRUARY 2005 – REVISED APRIL 2013 LM108AJAN Operational Amplifiers Check for Samples: LM108AJAN 1 FEATURES DESCRIPTION The LM108 is a precision operational amplifier having 2 • Maximum Input Bias Current of 3.0 nA over specifications a factor of ten better than FET Temperature amplifiers over a −55°C to +125°C temperature • Offset Current less than 400 pA over range. Temperature The devices operate with supply voltages from ±2V to • Supply Current of only 300 μA, even in ±20V and have sufficient supply rejection to use Saturation unregulated supplies. Although the circuit is • Ensured Drift Characteristics 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 makes possible many designs that are not practical with conventional amplifiers. In fact, it operates from 10 M Ω source resistances, introducing less error than devices such as the 709 with 10 k Ω sources. Integrators with drifts less than 500 μV/sec and analog time delays in excess of one hour can be made using capacitors no larger than 1 μF.
