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 500A
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
±1V to ±6V dual supply user. 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. 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
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/
s,lowpowerdissipationof0.5mW,lowoffsetvoltageandtemperature
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.
