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 V maximum frees the user from external nulling in most circuits. An open-loop gain of two million into a 10 k load ensures that excellent linearity is maintained even in high gain configurations, and 5 mA of output current allows 2 k 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. REV. C Information furnished by Analog Devices is believed to be accurate and reliable.

C PM1012 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 JA is specified for worst case mounting conditions, i.e., JA is specified for device in socket for cerdip, and P-DIP packages; JA is specified for device soldered to printed circuit board for SO package.

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. REV. C -3- WARNING!
