FEATURES
DESCRIPTIO
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
improvedwhencomparedtoequivalentgradesofcom-
peting precision amplifiers.

Essentially, the input offset voltage of all units is less
than 50µV (see distribution plot below). This allows the
LT1001AM/883 to be specified at 15µV. 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 10mA of load current. For similar perfor-
mance in a dual precision op amp, with guaranteed
matchingspecifications, seetheLT1002. Shownbelow
is a platinum resistance thermometer application.

of operation. Excluding the initial hour of operation, changes in V during
the first 30 days are typically 2.5µV.

Note 2: 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.
100% tested at 10Hz are available on request.

Unless proper care is exercised, thermocouple effects
caused by temperature gradients across dissimilar metals
at the contacts to the input terminals, can exceed the
inherent drift of the amplifier. Air currents over device
leads should be minimized, package leads should be
short, and the two input leads should be as close together
as possible and maintained at the same temperature.
APPLICATIONS INFORMATION
Application Notes and Test Circuits
The LT1001 series units may be inserted directly into
OP-07, OP-05, 725, 108A or 101A sockets with or without
removal of external frequency compensation or nulling
components. The LT1001 can also be used in 741, LF156
or OP-15 applications provided that the nulling circuitry is
removed.

Offset Voltage Adjustment
adjusted to 300 µV, the change in drift will be 1 µV/°C. The
adjustment range with a 10k or 20k pot is approximately
±2.5mV.Iflessadjustmentrangeisneeded,thesensitivity
and resolution of the nulling can be improved by using a
smaller pot in conjunction with fixed resistors. The ex-
ample below has an approximate null range of ±100 µV.
The input offset voltage of the LT1001, and its drift with
temperature, are permanently trimmed at wafer test to a
low level. However, if further adjustment of Vos is neces-
sary, nulling with a 10k or 20k potentiometer will not
degrade drift with temperature. Trimming to a value other
than zero creates a drift of (Vos/300)µV/°C, e.g., if Vos is
