Tel: 781/329-4700 World Wide Web Site: http://www.analog.com Fax: 781/326-8703 © Analog Devices, Inc., 1998 Low Power Precision Operational Amplifier FEATURES Low Supply Current: 600 A Max Very Low Offset: 35 V Max Low Drift: 1.5 V/ C Max Very Low Bias Current 25 C: 100 pA Max Low Noise: 0.5 V p-p Typ High Common-Mode Rejection: 114 dB Min 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 ±80 pA, typical, over the full military temperature range, and 132 dB of com- mon-mode rejection and power-supply rejection. The PM1012’s low offset voltage of 35 µV maximum frees the user from exter- nal nulling in most circuits. An open-loop gain of two million into a 10 k Ω load ensures that excellent linearity is maintained even in high gain configura- tions, and 5 mA of output current allows 2 k Ω 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 PIN CONNECTIONS Plastic Mini-DIP (P Suffix) 8-Lead SO (S Suffix) 8 7 6 5 1 2 3 4 NULL –IN +IN NULL V+ OUT OVER COMP V– PM1012 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 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. |
