CA124, CA224, CA324, LM324, LM2902
Quad, 1MHz, Operational Amplifiers for
Commercial, Industrial, and Military
Applications
The CA124, CA224, CA324, LM324, and LM2902 consist of
four independent, high-gain operational amplifiers on a
single monolithic substrate. An on-chip capacitor in each of
the amplifiers provides frequency compensation for unity
gain. These devices are designed specially to operate from
either single or dual supplies, and the differential voltage
range is equal to the power-supply voltage. Low power drain
and an input common-mode voltage range from 0V to V+
-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 input current will only exist when the voltage at any of the input leads is driven negative. This current is due to the collector base junction of the
input p-n-p transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral n-p-n
parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the amplifiers to go to the V+ voltage level (or to ground
for a large overdrive) for the time duration that an input is driven negative. This transistor action is not destructive and normal output states will re-
establish when the input voltage, which was negative, again returns to a value greater than -0.3V.
2. The maximum output current is approximately 40mA independent of the magnitude of V+. Continuous short circuits at V+ > 15V can cause
excessive power dissipation and eventual destruction. Short circuits from the output to V+ can cause overheating and eventual destruction of
the device.
3. θJA is measured with the component mounted on an evaluation PC board in free air.
Electrical Specifications Values Apply for Each Operational Amplifier. Supply Voltage V+ = 5V, V- = 0V,

NOTES:
4. Due to the PNP input stage the direction of the input current is out of the IC. No loading change exists on the input lines because the current is
essentially constant, independent of the state of the output.
5. The input signal voltage and the input common mode voltage should not be allowed to go negative by more than 0.3V. The positive limit of the
common mode voltage rangeis V+ - 1.5V, but either or both inputs can go to +32V without damage.
6. VO=1.4V,R
S=0Ωwith V+ from 5V to 30V, and over the full input common mode voltage range (0V to V+ - 1.5V).
