www.fairchildsemi.com
Features
• Low input bias current — 2 nA
• Low input offset current — 200 pA
• Low input offset voltage — 500mV
• Low input offset drift — 5 mV/°C
• Wide supply range — ±3V to ±20V
• Low supply current — 0.6 mA
• High PSRR — 96 dB
• High CMRR — 96 dB
• MIL-STD-883B available
Description
The LM108A operational amplifiers features low input bias
current combined with the advantages of bipolar transistor
construction; input offset voltages and currents are kept
low over a wide range of temperature and supply voltage.
Fairchild Semiconductor’s superbeta bipolar manufacturing
process includes extra treatment at epitaxial growth to ensure
low input voltage noise.
The LH2108 consists of two LM108 ICs in one 16-lead DIP.
The “A” versions meet tighter electrical specifications than
the plain versions. All types are available with 883B military
screening.

PRODUCT SPECIFICATION
Notes:
1. Index area: a notch or a pin one identification mark shall be located
adjacent to pin one. The manufacturer's identification shall not be
used as pin one identification mark.
2. The minimum limit for dimension "b2" may be .023 (.58mm) for leads
number 1, 4, 5 and 8 only.
3. Dimension "Q" shall be measured from the seating plane to the base
plane.
4. This dimension allows for off-center lid, meniscus and glass overrun.
5. The basic pin spacing is .100 (2.54mm) between centerlines. Each
pin centerline shall be located within ±.010 (.25mm) of its exact
longitudinal position relative to pins 1 and 8.
6. Applies to all four corners (leads number 1, 4, 5, and 8).
7. "eA" shall be measured at the center of the lead bends or at the
centerline of the leads when "a" is 90¡.
8. All leads – Increase maximum limit by .003 (.08mm) measured at the
center of the flat, when lead finish applied.
9. Six spaces.
