LM108A/LM208A/LM308A Operational Amplifiers

General Description

The LM108/LM108A series are precision operational ampli-

fiers having specifications about a factor of ten better than

FET amplifiers over their operating temperature range. In

addition to low input currents, these devices have extremely

low offset voltage, making it possible to eliminate offset ad-

justments, in most cases, and obtain performance ap-

proaching chopper stabilized amplifiers.

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 us-

ing capacitors no larger than 1 mF.

The LM208A is identical to the LM108A, except that the

LM208A has its performance guaranteed over a 25 C to

85 C temperature range, instead of 55 C to 125 C.

The LM308A devices have slightly-relaxed specifications

18V and have sufficient supply rejection to use unregulat-

The devices operate with supply voltages from

2V to

and performances over a 0 C to 70 C temperature range.

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.

Features

Offset voltage guaranteed less than 0.5 mV

Maximum input bias current of 3.0 nA over temperature

Offset current less than 400 pA over temperature

Supply current of only 300 mA, even in saturation

The low current error of the LM108A series makes possible

many designs that are not practical with conventional ampli-

fiers. In fact, it operates from 10 MX source resistances,
