The LT
1001 significantly advances the state-of-the-
art of precision operational amplifiers. In the design,
processing, and testing of the device, particular atten-
tion has been paid to the optimization of the entire
distribution of several key parameters. Consequently,
the specifications of the lowest cost, commercial tem-
perature device, the LT1001C, have been dramatically
improved when compared to equivalent grades of com-
peting precision amplifiers.
Essentially, the input offset voltage of all units is less
than 50
μ
V (see distribution plot below). This allows the
LT1001AM/883 to be specified at 15
μ
V. Input bias and
offset currents, common-mode and power supply re-
jection of the LT1001C offer guaranteed performance
which were previously attainable only with expensive,
selected grades of other devices. Power dissipation is
nearly halved compared to the most popular precision
op amps, without adversely affecting noise or speed
performance. A beneficial by-product of lower dissipa-
tion is decreased warm-up drift. Output drive capability
of the LT1001 is also enhanced with voltage gain
guaranteed at 10 mA of load current. For similar perfor-
mance in a dual precision op amp, with guaranteed
matching specifications, see the LT1002. Shown below
is a platinum resistance thermometer application.
