| Data Sheet LOW POWER QUAD OPERATIONAL AMPLIFIERS General Description The AS324/324A consist of four independent, high gain and internally frequency compensated operational amplifiers. They are specifically designed to operate from a single power supply. 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. Typical applications include transducer amplifiers, DC gain blocks and most conventional operational amplifier circuits. The AS324/324A series are compatible with industry standard 324. AS324A has more stringent input offset voltage than AS324. The AS324 is available in SOIC-14, DIP-14 and TSSOP-14 packages, AS324A is available in SOIC-14 and DIP-14 packages.
