Quad, 1MHz, Operational Amplifiers for
Commercial, Industrial, and Military
Applications
itle
The CA124,CA224, CA324, LM324, and LM2902 consist of
12
four independent, high-gainoperational amplifiers on a
single monolithic substrate. An on-chip capacitor in each of
224
the amplifiers provides frequency compensationfor unity
gain. These devices are designed specially to operatefrom
324
either single or dual supplies, and the differential voltage
range is equal tothe power-supplyvoltage. Low power drain
and an inputcommon-mode voltage range from 0V to V+
324
-1.5V (single-supply operation) make these devices suitable
for battery operation.
CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operationofthe
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. This inputcurrent will onlyexist when the voltage at any of theinput leads is driven negative. This currentis due to the collectorbase junction of the
input p-n-p transistorsbecoming forward biased and thereby actingas input diode clamps.In additionto this diode action, thereis also lateral n-p-n
parasitictransistor action on the ICchip.Thistransistoractioncan cause the output voltagesof the amplifiers to go totheV+voltagelevel (or to ground
for a large overdrive) for the time duration that an input is driven negative. Thistransistoraction isnot destructive and normal outputstates will reestablishwhen theinput voltage, whichwas negative, again returns to a valuegreater than -0.3V.
2. The maximum output current is approximately 40mA independentof the magnitudeof V+. Continuousshortcircuits at V+ > 15V can cause
excessive power dissipationand eventual destruction. S hort circuits from theoutput to V+ can cause overheating andeventual destruction of
the device.
3. θ
is measured with thecomponent mountedon an evaluation PC board in freeair.

NOTES:
4. Due to t he PNP inputstage the directionof the input currentis out ofthe IC. No loading change existson theinput lines because the currentis
essentially constant, independentof the state ofthe output.
5. The input signal voltageand the input common mode voltageshouldnot be allowed to go negativeby more than0.3V. T he positivelimit of the
commonmode voltage range is V+ - 1.5V, but either or both inputs can go to +32V without damage.
