AS324N
Low Power Quad Operational Amplifier
General Description
The AS324N series consists of four independent, high gain, internally frequency compen-
sated operational amplifiers which were designed specifically to operate from a single
power supply over a wide range of voltages. 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.
Application areas include transducer amplifiers, DC gain blocks and all the conventional
op amp circuits which now can be more easily implemented in single power suplly
systems. For example, the AS324N series can be directly operated off of the standard
+5 V power supply voltage which is used in digital systems and will easily provide the
requDirCed interface electronics without requiring the additional ±15 VDC power supply.
Unique Characteristics
• In the linear mode the input common-mode voltage range includes ground and the
output voltage can also swing to ground, even though operated from only a single power
supply voltage.
• The unity gain cross frequency is temperature compensated.
• The input bias current is also temperature compensated.
Advantages
• Eliminated need for dual supplies.
• Four internally compensated op amps in a single package.
• Allows directly sensing near GND and V also goes to GND.
• Compatible with all forms of logic.
OUT
• Power drain suitable for battery operation.
Features
• Internally frequency compensated for unity gain.
• Large DC voltage gain
100 dB
• Wide bandwidth (unity gain)
1 MHz
(temperature compensated)
• Wide power supply range:
Single supply
3 V to 32 V

or dual supplies
±1,5 VDC to ±16 VDC
• Very low supply current drain (700 µA) - essentially independent of supply
voltage.
• Low input biasing current
(temperature compensated)

• Low input offset voltage

• Input common-mode voltage range includes ground.
• Differential input voltage equal to the power supply voltage.
