Description
The AP358 series consists of two independent, high gain,
internally frequency compensated 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 supply systems.
For example, the AP358 series can be directly operated off of
the standard +5V power supply voltage which is used in
digital systems and will easily provide the required interface
electronics without requiring the additional ±15V power
supply.
Features
• Internally frequency compensated for unity gain
• Large dc voltage gain: 100 dB
• Very low supply current drain (500μA)-essentially
independent of supply voltage
• Wide bandwidth (unity gain): 1 MHz (temperature
compensated)
• Input common-mode voltage range includes ground
• Differential input voltage range equal to the power supply
voltage
• Low input offset voltage: 2mV
• Wide power supply range:
• Single supply: 3V to 32V
• Or dual supplies: ±1.5V to ±16V
• Large output voltage swing: 0V to V
+
- 1.5V
• Lead Free packages: SOP-8L and PDIP-8L
• SOP-8L and PDIP-8L: Available in “Green” Molding
Compound (No Br, Sb)
• Lead Free Finish/ RoHS Compliant (Note 1)

Application
• Eliminate the need for dual supplies
• Compatible with all forms of logic
• Two internally compensated op amps
• Low power drain suitable for battery operation
• Allows direct sensing near GND and V
OUT
also goes to
GND
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 compensate.
