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.
