Low Power Dual Operational Amplifiers
AP358
„ Features
„ General Description
- 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
- 8-pin PDIP and SOP Pb-Free packages
„ Advantages
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 supplies.
- Eliminates need for dual supplies
- Compatible with all forms of logic
- Two internally compensated op amps
- 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
compensated.
