LM124
LM224 - LM324
LOW POWER QUAD OPERATIONAL AMPLIFIERS
■ WIDE GAIN BANDWIDTH : 1.3MHz
■ INPUT COMMON-MODE VOLT AGE RANGE
INCLUDES GROUND
■ LARGE VOLTAGE GAIN : 100dB
■ VERY LOW SUPPLY CURRENT/AMPLI :
375µA
■ LOW INPUT BIAS CURRENT : 20nA
■ LOW INPUT OFFSET VOLTAGE : 5mV max.
(for more accurate applications, use the equivalent parts LM124A-LM224A-LM324A which
feature 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 t he
low power supply current drain is independent of
the magnitude of the power supply voltage.

1. Either or both input voltages must not exceed the magnitude of V
2. Short-circuits from the output to VCC can cause excessive heating if VCC > 15V. The maximum output current is approximately 40mA independent
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 ther eby acti ng as input diodes clamps. In additi on to t his diode acti on, ther e is also NPN parasitic act ion on

1. Vo = 1.4V, Rs = 0Ω, 5V < V
2. The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output so no loading change
exists on the input lines.
3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the
common-mode voltage range is V
4. Due to the proximity of external components insu re that coupli ng is not origina ting via s tray capaci tance bet ween these ext ernal parts. This typically
can be detected as this type of capacitance increases at higher frequences.
