GENERAL DESCRIPTION

The ALD2701A/ALD2701B/ALD2701 is a dual monolithic CMOS

micropower high slew rate operational amplifier intended for a broad

range of analog applications using ±1V to ±5V dual power supply systems,

as well as +2V to +10V battery operated systems.

All device

characteristics are specified for +5V single supply or ±2.5V dual supply

systems. Supply current is 500µA maximum at 5V supply voltage. It is

manufactured with Advanced Linear Devices' enhanced ACMOS silicon

gate CMOS process.

The ALD2701A/ALD2701B/ALD2701 is designed to offer a trade-off of

performance parameters providing a wide range of desired specifications.

It has been developed specifically for the +5V single supply or ±1V to

±5V dual supply user and offers the popular industry standard pin

configuration of µA741 and ICL7621 types.

Several important characteristics of the 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. Second, each device was designed

to accommodate mixed applications where digital and analog circuits

may operate off the same power supply or battery. Third, the output

stage can typically drive up to 50pF capacitive and 10KΩ resistive loads.

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/µs, low power dissipation of 0.5mW, low offset voltage and

temperature drift, make the ALD2701A/ALD2701B/ALD2701 a versatile,

micropower dual operational amplifier.

The ALD2701A/ALD2701B/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. Additionally, robust design and rigorous screening make this

device especially suitable for operation in temperature-extreme

environments and rugged conditions.
