BCD AS324G-E1 Low power quad operational amplifier Datasheet

Data Sheet
LOW POWER QUAD OPERATIONAL AMPLIFIERS
General Description
Features
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.

Electrical Characteristics (Continued)
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.
