The 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.
♦ Guaranteed Low Offset Voltage
MXL1001AM: 15µV max
MXL1001C: 60µV max
♦ Guaranteed Low Drift
MXL1001AM: 0.6µV/°C max
MXL1001C: 1.0µV/°C max
♦ Guaranteed Low Bias Current
MXL1001AM: 2nA max
MXL1001C: 4nA max
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.
♦ Guaranteed CMRR
MXL1001AM: 114dB min
MXL1001C: 110dB min
♦ Guaranteed PSRR
MXL1001AM: 110dB min
MXL1001C: 106dB min
♦ Low Power Dissipation
MXL1001AM: 75mW max
MXL1001C: 80mW max

Note 1: For supply voltages less than ±22V, the absolute maximum input voltage is equal to the supply voltage.
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.

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.

change in drift will be 1µV/°C. The adjustment range
with a 10kΩ or 20kΩ potentiometer is approximately

by using a potentiometer of lower ohmic value in con-
junction with fixed resistors.
