Product Summary

The LM124J is a Low Power Quad Operational Amplifier. The LM124J consists of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to 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.

Parametrics

LM124J absolute maximum ratings: (1)Supply Voltage, V+: 32Vdc or +16Vdc; (2)Differential Input Voltage: 32Vdc; (3)Input Voltage: -0.3Vdc to +32Vdc; (4)Input Current (VIN < -0.3Vdc): 50 mA; (5)Power Dissipation: 1260mW; (6)Output Short-Circuit to GND (One Amplifier), V+≤ 15Vdc and TA = 25℃: Continuous; (7)Operating Temperature Range: -55℃ ≤ TA ≤ +125℃; (8)Maximum Junction Temperature: 150℃; (9)Storage Temperature Range: -65℃ ≤ TA ≤ +150℃; (10)Lead Temperature (Soldering, 10 seconds): 260℃; (11)Thermal Resistance ThetaJA: 103℃/W; (12)ESD Tolerance: 250V.
