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
V (see distribution plot below). This allows the
LT1001AM/883 to be specified at 15
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.

The
q
denotes the specifications which apply over the full operating
temperature range.
Note 1: Offset voltage for the LT1001AM/883 and LT1001AC are measured
after power is applied and the device is fully warmed up. All other grades
are measured with high speed test equipment, approximately 1 second
after power is applied. The LT1001AM/883 receives 168 hr. burn-in at
125
C. or equivalent.
Note 2: This parameter is tested on a sample basis only.
Note 3: Long Term Input Offset Voltage Stability refers to the averaged
trend line of V
OS
versus Time over extended periods after the first 30 days
of operation. Excluding the initial hour of operation, changes in V
OS
during
the first 30 days are typically 2.5
V.
Note 4: Parameter is guaranteed by design.
Note 5: 10Hz noise voltage density is sample tested on every lot. Devices
100% tested at 10Hz are available on request.
