LM108AJAN Datasheet | National Semiconductor

Description 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 pensation as the LM101A, an alternate pensation 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 MΩ source resistances, introducing less error than devices such as the 709 with 10 kΩ 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. Features - Maximum input bias current of 3.0 n A over temperature - Offset current less than 400 p A over temperature - Supply current of only 300 μA, even in saturation - Guaranteed drift characteristics Ordering Information NS PART NUMBER JL108ABGA JL108ABPA JL108ABCA JL108ABHA JL108ABZA JL108ASGA JL108ASPA JL108ASCA JL108ASHA SMD PART NUMBER JM38510/10104BGA JM38510/10104BPA JM38510/10104BCA JM38510/10104BHA JM38510/10104BZA JM38510/10104SGA JM38510/10104SPA JM38510/10104SCA JM38510/10104SHA Connection Diagrams Metal Can Package NS PACKAGE NUMBER H08C J08A J14A W10A WG10A H08C J08A J14A W10A PACKAGE DISCRIPTION 8LD Metal Can 8LD CERDIP 14LD CERDIP 10LD CERPACK 10LD Ceramic SOIC 8LD Metal Can 8LD CERDIP 14LD CERDIP 10LD CERPACK Dual-In-Line Package - Package is connected to Pin 4 (V- ) - - Unused pin (no internal connection) to allow for input anti-leakage guard ring on printed circuit board layout.
