LM124, LM224x, LM324x Datasheet Low-power quad operational amplifiers Features Wide gain bandwidth: 1.3 MHz Input common mode voltage range includes ground QFN16 3x3 Large voltage gain: 100 dB Very low supply current/amplifier: 375 A Low input bias current: 20 nA Low input voltage: 3 mV max. TSSOP14 Low input offset current: 2 nA Wide power supply range: Single supply: 3 V to 30 V Dual supplies: 1.5 V to 15 V SO14 Related products See TSB572 and TSB611, 36 V newer technology devices, which have enhanced accuracy and ESD rating, reduced power consumption, and automotive grade qualification See LM2902 and LM2902W for automotive grade applications Description The LM124, LM224x and LM324x consist of four independent, high gain operational amplifiers with frequency compensation implemented internally. They operate from a Product status link single power supply over a wide range of voltages. LM124, LM224x, LM324x 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.
