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 (500

μA)-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

•

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.
