LOW POWER QUAD OPERATIONAL AMPLIFIERS AS324/324A

Figure 1. Package Types of AS324/324A

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

package.

Note 3: The input common-mode voltage of either input signal voltage should not be allowed to go negatively by

more than 0.3V (at 25oC). The upper end of the common-mode voltage range is VCC -1.5V (at 25oC), but either or

both inputs can go to +36V without damages, independent of the magnitude of the VCC.
