noise contributions when high source impedances are used. T he
PM1012 may be overcompensated, using Pin 5 to limit the
amplifier’s bandwidth, further reducing system noise and in-
creasing stability with large capacitive loads.
GENERAL D ESCRIP TIO N
T he PM1012 is a general purpose, precision operational ampli-
fier. Offering several performance enhancements over industry-
standard precision op amps such as the OP07, the PM1012
requires less than 1/6 the supply current. T hese enhancements
include exceptionally low bias currents of only ±80 pA, typical,
over the full military temperature range, and 132 dB of com-
mon-mode rejection and power-supply rejection. T he PM1012’s
low offset voltage of 35 µV maximum frees the user from exter-
nal nulling in most circuits.
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. T he PM1012 may
replace 741 type op amps by removing the nulling potentiom-
eter, if used.
An open-loop gain of two million into a 10 kΩ load ensures that
excellent linearity is maintained even in high gain configura-
tions, and 5 mA of output current allows 2 kΩ loads to be
driven with an open-loop gain of one million. T he PM1012
offers low noise, especially for a low power amplifier—only
17 nV/√Hz at 10 Hz. Exceptionally low current noise minimizes

2For supply voltages less than ±20 V, the absolute maximum input voltage is equal
to the supply voltage.
3T he 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.

in socket for cerdip, and P-DIP packages; θJA is specified for device soldered to

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. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
