Precision Operational Amplifier
_______________General DescriptionThe MXL1001 offers significant specification improvement
over earlier precision operational amplifiers and is pin-
compatible with the industry-standard LT1001. Particular
attention has been paid to the optimization of key parame-
ters such as input offset voltage, common-mode rejection,
and power-supply rejection. In addition, the high-perfor-
mance MXL1001C commercial temperature device pro-
vides considerable cost savings when compared to
equivalent grades of competing precision amplifiers.
The input offset voltage of all units is less than 60µV,
allowing the premium military device, the MXL1001AM, to
be specified at 15µV max. Power dissipation is close to
half that of the industry-standard OP-07 precision op
amp, without sacrificing noise or speed performance. A
useful by-product of lower dissipation is decreased
warm-up drift.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS(VS= ±15V, TA= +25°C, unless otherwise noted.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 2:MXL1001A grade VOSis measured one minute after application of power. For all other grades VOSis measured
approximately 0.5 seconds after application of power.
Note 3:Long-Term Input Offset Voltage Stability refers to the average trend line of VOSvs. Time over extended periods after the first
30 days of operation. Excluding the initial hour of operation, changes in VOSduring the first 30 operating days are typically
2.5µV. Parameter is sample tested.
Note 4:Sample tested.
Note 5:Guaranteed by design.

MXL1001
Precision Operational AmplifierFigure 1.Optional Offset Nulling Circuit
__________Applications InformationThe MXL1001 series devices are pin-compatible with the
OP-07, OP-05, 725, 108A or 101A amplifiers. The
MXL1001 amplifiers can be used to upgrade older
designs using these devices, with or without removal of
external frequency compensation or nulling components.
The MXL1001 can also be used in 741, LF156 or OP-15
applications provided the nulling circuitry is removed.
The MXL1001 is specified over a wide supply voltage
range from ±3V to ±18V. Operation with lower supplies
is possible down to ±1.2V(two NiCd batteries), howev-
er, at this level the device is stable only in closed-loop
gains of +2 and above (or inverting gain of one or high-
er). Unless proper care is exercised, thermocouple
effects caused by temperature gradients across dissimi-
lar metals at the input terminal connections, can exceed
the inherent offset-voltage drift of the amplifier. Air cur-
rents over the device leads should be minimized, pack-
age leads should be short, and the two input leads
should be as close together as possible and maintained
at the same temperature.
Offset-Voltage AdjustmentThe input offset voltage of the MXL1001, and its temper-
ature drift, are minimized by zener-zap trimming at the
wafer level. If further nulling of VOSis required, this can
be performed using a 10kΩor 20kΩpotentiometer with
no degradation of VOSdrift with temperature. Trimming
to a value other than zero creates a drift of
(VOS/300)µV/°C; i.e., if VOSis adjusted to 300µV, the
change in drift will be 1µV/°C. The adjustment range
with a 10kΩor 20kΩpotentiometer is approximately
±2.5mV. If less adjustment range is needed, the sensi-
tivity and resolution of the offset nulling can be improved
by using a potentiometer of lower ohmic value in con-
junction with fixed resistors.
