GENERAL DESCRIPTION

The ALD2701 is a dual monolithic CMOS micropower high slew rate

operational amplifier intended for a broad range of analog applications

using 1V to 6V dual power supply systems, as well as +2V to +12V

battery operated systems. All device characteristics are specified for +5V

single supply or 2.5V dual supply systems. Supply current is 500 A

maximum at 5V supply voltage. It is manufactured with Advanced Linear

Devices' enhanced ACMOS silicon gate CMOS process.

The ALD2701 is designed to offer a trade-off of performance parameters

providing a wide range of desired specifications. It offers the popular

industry standard pin configuration of A747 and ICL7621 types.

The ALD2701 has been developed specifically for the +5V single supply or

device make application easier to implement at those voltages.

First, each operational amplifier can operate with rail-to-rail input and

output voltages. This means the signal input voltage and output voltage

can be equal to the positive and negative supply voltages. This feature

allows numerous analog serial stages and flexibility in input signal bias

levels. Secondly, each device was designed to accommodate mixed

applications where digital and analog circuits may operate off the same

power supply or battery. Thirdly, the output stage can typically drive up to

50pF capacitive and 10K

These features, combined with extremely low input currents, high open

loop voltage gain of 100V/mV, useful bandwidth of 700KHz, a slew rate of

0.7V/ s, low power dissipation of 0.5mW, low offset voltage and temperature

drift, make the ALD2701 a versatile, micropower dual operational amplifier.

The ALD2701, designed and fabricated with silicon gate CMOS technology,

offers 1pA typical input bias current. On chip offset voltage trimming allows

the device to be used without nulling in most applications.

Due to low voltage and low power operation, reliability and operating

characteristics, such as input bias currents and warm up time, are greatly

improved.
