NOTES
¹Absolute maximum ratings apply to both DICE and packaged parts, unless otherwise noted.
²For supply voltages less than ±20 V, the absolute maximum input voltage is equal to the supply voltage.
³The 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_JA is specified for worst case mounting conditions, i.e., _JA is specified for device in socket for cerdip, and P-DIP packages; qJA is specified for device soldered to printed circuit board for SO package.

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 mV maximum frees the user from external nulling in most circuits.

An open-loop gain of two million into a 10 kW load ensures that excellent linearity is maintained even in high gain configurations, and 5 mA of output current allows 2 kW 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/ÖHz at 10 Hz. Exceptionally low current noise minimizes 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.
