GENERAL DESCRIPTION
The ALD2711A/ALD2711B/ALD2711 is a dual monolithic CMOS
micropower precision 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. Typical supply current is 200µA at 5V supply
voltage. It is manufactured with Advanced Linear Devices' enhanced
ACMOS silicon gate CMOS process.
The ALD2711A/ALD2711B/ALD2711 has been developed specifically
for the +5V single supply or ±1V to ±5V dual supply user and has an
input stage that operates to +300mV above and -300mV below the
supply voltages with no adverse effects and/or phase reversals.
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 at 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, high useful bandwidth, and slew rate make the
LD2711A/ALD2711B/ALD2711 a versatile, micropower operational
amplifier.
The ALD2711A/ALD2711B/ALD2711 with on-chip offset voltage trimming
allows the device to be used without nulling in most applications.
Additionally, robust design and rigorous screening make this device
especially suitable for operation in temperature-extreme environments and
rugged conditions.
The unique characteristics of the ALD2711A/ALD2711B/ALD2711 are
modeled in an available macromodel.
