• Supply voltage ±5.0V to ±20V
Description
The LM101A/LH2101A is a general purpose high perfor-
mance operational amplifier fabricated monolithically on a
silicon chip by an advanced epitaxial process. The LH2101A
consists of two LM101A ICs in one 16-lead DIP. The units
may be fully compensated with the addition of a 30 pF
capacitor stabilizing the circuit for all feedback configura-
tions including capacitive loads.
The device may be operated as a comparator with a differen-
tial input as high as 30V. Used as a comparator the output
can be clamped at any desired level to make it compatible
with logic circuits.
The LM101A and LH2101A operate over the full military
temperature range from -55°C to +125°C.

L2 & .500 (12.70mm) from the reference plane. Diameter is
uncontrolled in L1 & beyond .500 (12.70mm) from the
reference plane.
Measured from the maximum diameter of the product.
Leads having a maximum diameter .019 (.48mm) measured in
gauging plane, .054 (1.37mm) +.001 (.03mm) –.000 (.00mm)
below the reference plane of the product shall be within
.007 (.18mm) of their true position relative to a maximum width
tab.
The product may be measured by direct methods or by gauge.
All leads – increase maximum limit by .003 (.08mm) when lead
finish is applied.

The minimum limit for dimension "b2" may be .023 (.58mm) for leads
number 1, 4, 5 and 8 only.
Dimension "Q" shall be measured from the seating plane to the base
plane.
This dimension allows for off-center lid, meniscus and glass overrun.
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.
Applies to all four corners (leads number 1, 4, 5, and 8).
"eA" shall be measured at the center of the lead bends or at the
centerline of the leads when "a" is 90¡.
All leads – Increase maximum limit by .003 (.08mm) measured at the
