The LM324 contains four independent high gain operational amplifiers with internal frenquency compensation.The four op-amps operate over a wide voltage range from a single power supply.Also use a split power supply.The device haslow power supply current drain,regardless of the power supplyvoltage.The low power drain also makes the LM324 a good choice for battery operation.

Note 1: Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the Recommended Operating Conditions. Power Derating: DIP Package:-10mW/ from 65 to 125 SOP Package:-7mW/ from 65 to 125Note 2: Split Power Supplies.Note 3: VIN<-0.3V.This input current will only exist when voltage at any of the input leads is driven negative.

RECOMMENDED OPERATING CONDITIONS

Notes:This device contains protection circuitry to guard against damage due to high static volt- ages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC.
