LOW POWER QUAD OPERATIONAL AMPLIFIERS
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.
The AS324A has more stringent input offset voltage than AS324.
The AS324 is available in SOIC-14, DIP-14 and TSSOP-14
packages, and the AS324A is available in SOIC-14 package.
