GENERAL DESCRIPTION
The PM1012 is a general purpose, precision operational amplifier. Offering several performance enhancements over industrystandard precision op amps such as the OP07, the PM1012
requires less than 1/6 the supply current. These enhancements
include exceptionally low bias currents of only ± 80 pA, typical,
over the full military temperature range, and 132 dB of common-mode rejection and power-supply rejection. The PM1012’s
low offset voltage of 35 µV maximum frees the user from external nulling in most circuits.
An open-loop gain of two million into a 10 kΩ load ensures that
excellent linearity is maintained even in high gain configurations, and 5 mA of output current allows 2 kΩ loads to be
driven with an open-loop gain of one million. The PM1012
offers low noise, especially for a low power amplifier—only
17 nV/√Hz at 10 Hz. Exceptionally low current noise minimizes
PM1012
5
noise contributions when high source impedances are used. The
PM1012 may be overcompensated, using Pin 5 to limit the
amplifier’s bandwidth, further reducing system noise and increasing stability with large capacitive loads.
The PM1012 conforms to the OP07 pinout with nulling through
Pins 1 and 8 to the positive supply. It offers an upgrade to the
OP07 in sockets where reduced power dissipation or low bias
currents are attractive. It may also be used as an upgrade from
the OP12, OP05 and 725 type op amps. The PM1012 may
replace 741 type op amps by removing the nulling potentiometer, if used.

ABSOLUTE MAXIMUM RATINGS 1
NOTES
1
Absolute maximum ratings apply to both DICE and packaged parts, unless
otherwise noted.
2
For supply voltages less than ±20 V, the absolute maximum input voltage is equal
to the supply voltage.
3
The PM1012’s inputs are protected by back-to-back diodes. Current-limiting
resistors are not used in order to achieve low noise. Differential input voltages
greater than 1 V will cause excessive current to flow through the input protection
diodes unless limiting resistance is used.
4
θJA is specified for worst case mounting conditions, i.e., θJA is specified for device
in socket for cerdip, and P-DIP packages; θJA is specified for device soldered to
printed circuit board for SO package.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the PM1012 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
