LM124-LM224-LM324 are low power quad operational amplifiers. Their features are: bandwidth of 1.3 MHz, input common-mode voltage range includes ground, voltage gain of 100 dB, supply current per amplifier very low at 375 µA, input bias current of 20 nA, input offset voltage of 5 mV max. (For more accurate applications, use the equivalent parts LM124A-LM224A-LM324A which feature 3 mV max.), wide power supply range: single supply: +3 V to +30 V; dual supplies: ±1.5 V to ±15 V.
The LM124, LM224 and LM324 are low‑power quad operational amplifiers with a wide gain‑bandwidth of 1.3 MHz, low supply current (375 µA per amplifier) and input bias currents as low as 20 nA. They operate from a single supply of +3 V to +30 V (or dual supplies of +1.5 V to +15 V) and cover a broad temperature range.
The handbook includes features, order codes, pin‑out diagrams, absolute maximum ratings, detailed electrical characteristics, package information, macromodels and revision history, providing designers with the data needed for circuit design and verification.
