GENERAL DESCRIPTION
The 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. These enhancements
include exceptionally low bias currents of only
鹵
80 pA, typical,
over the full military temperature range, and 132 dB of com-
mon-mode rejection and power-supply rejection. The PM1012鈥檚
low offset voltage of 35
碌V
maximum frees the user from exter-
nal nulling in most circuits.
An open-loop gain of two million into a 10 k鈩?load ensures that
excellent linearity is maintained even in high gain configura-
tions, and 5 mA of output current allows 2 k鈩?loads to be
driven with an open-loop gain of one million. The PM1012
offers low noise, especially for a low power amplifier鈥攐nly
17 nV/鈭欻z 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鈥檚 bandwidth, further reducing system noise and in-
creasing 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 potentiom-
eter, if used.
