CA124, CA224, CA324
LM324*, LM2902*
Quad Operational Amplifiers for
Commercial, Industrial, and Military Applications
Description
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.
The CA124, CA224, CA324, LM324 and LM2902 are
supplied in both 14-lead dual-in-line plastic (E suffix) and
14-lead (150 mil) small outline (M suffix) packages. The
CA324 is available in chip form (H suffix).

Differential Input Voltage
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
DC
.
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 destruc-
tion of the device.
3. Due to the p-n-p 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.
4. 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 range is V+ - 1.5V, but either or both inputs can go to +32V without damage.
