ALD2706A/ALD2706B
ALD2706
DUAL ULTRA MICROPOWER RAIL-TO-RAIL CMOS OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
The ALD2706A/ALD2706B/ALD2706 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 80µA maximum at 5V supply voltage. It is manufactured with
Advanced Linear Devices' enhanced A CMOS silicon gate CMOS process.
The ALD2706A/ALD2706B/ALD2706 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.
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 25pF capacitive and 20KΩ resistive loads. These
features, combined with extremely low input currents, high open loop
voltage gain of 100V/mV, useful bandwidth of 200KHz, a slew rate of 0.1V/
µs,
low offset voltage and temperature drift, make the ALD2706A/
ALD2706B/ALD2706 a versatile, micropower dual operational amplifier.
A typical ALD2706A/ALD2706B/ALD2706 has the capacity to process a
0.998V amplitude analog signal with only 1.000V single supply voltage,
while requiring only 0.1pA input bias current. Additionally, robust design
and rigorous screening make this device especially suitable for operation
in temperature-extreme environments and rugged conditions.
