LM324

JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD SOP14 Plastic-Encapsulate Operational Amplifiers LM324 Low Power Q uad Operational Amplifier DESCRIPTION SOP14 The LM324 consists of four independent, high gain and internally frequency compensated operational amplifiers, it is specifically designed to operate from a single power supply. Operation from split power sup-ply is also possible and the low power supply current drain is independent of the magnitude of the power supply voltages. · Internally Frequency Compensated for Unity Gain Large Voltage Gain: 100dB (Typical) Low Input Bias Current: 45nA (Typical) Low Input Offset Voltage: 2mV (Typical) Low Supply Current: 0.5mA (Typical) Wide Power Supply Voltage Range: Single Supply: 3V to 30V Dual Supplies:± 1.5V to ± 15V Input Common Mode Voltage Range Includes Ground Large Output Voltage Swing: 0V to VCC-1.5V · Power Drain Suitable for Battery Operation · 1 14 OUTPUT 4 INPUT 1- 2 13 INPUT 4- INPUT 1+ 3 12 INPUT 4+ VCC 4 11 GND 5 10 INPUT 3+ INPUT 2+ Features · · · · · · OUTPUT 1 INPUT 2- 6 9 INPUT 3- OUTPUT 2 7 8 OUTPUT 3 Applications · · · Battery Charger Cordless Telephone Switching Power Supply Functional Block Diagram VCC 6µA 4µA 100µA Q5 Q6 Q2 INPUT- Q3 Cc Q7 Q4 Q1 Rsc OUTPUT INPUT+ Q11 Q10 Q8 Q9 Q13 Q12 50µA Figure 1.
