LM124W-LM224W-LM324W
Low Power Quad Operational Amplifiers
Wide gain bandwidth: 1.3MHz
Input common-mode voltage range includes
ground
Large voltage gain: 100dB
Very low supply current/ampli: 375µA
Low input bias current: 20nA
Low input offset voltage: 3mV max.
Low input offset current: 2nA
Wide power supply range:
Single supply: +3V to +30V
Dual supplies: ±1.5V to ±15V
Description
These circuits consist of four independent, high
gain, internally frequency compensated
operational amplifiers. They operate from a single
power supply over a wide range of voltages.
Operation from split power supplies is also
possible and the low power supply current drain is
independent of the magnitude of the power supply
voltage.
All the pins are protected against electrostatic
discharges up to 2000V (as a consequence, the
input voltages must not exceed the magnitude of
VCC+ or VCC-.)

1. Either or both input voltages must not exceed the magnitude of VCC+ or VCC-.
2. Short-circuits from the output to VCC can cause excessive heating if VCC > 15V. The maximum output current
is approximately 40mA independent of the magnitude of VCC. Destructive dissipation can result from
simultaneous short-circuit on all amplifiers.
3. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the
collector-base junction of the input PNP transistor becoming forward biased and thereby acting as input diodes
clamps. In addition to this diode action, there is also NPN parasitic action on the IC chip. this transistor action
can cause the output voltages of the op-amps to go to the VCC voltage level (or to ground for a large overdrive)
for the time duration than an input is driven negative.
This is not destructive and normal output will set up again for input voltage higher than -0.3V.
4. Human body model, 100pF discharged through a 1.5kresistor into pin of device.
5. Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with
no external series resistor (internal resistor < 5), into pin to pin of device.
