ALD1706A/ALD1706B
ALD1706/ALD1706G
ULTRA MICROPOWER RAIL-TO-RAIL CMOS OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
The ALD1706A/ALD1706B/ALD1706/ALD1706G is a monolithic CMOS
ultra micropower high slew-rate, high performance 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 40µA maximum at 5V supply
voltage. It is manufactured with Advanced Linear Devices' enhanced
ACMOS silicon gate CMOS process.
The ALD1706A/ALD1706B/ALD1706/ALD1706G is designed to offer high
performance for a wide range of applications requiring very low power
dissipation. It has been developed specifically for the +5V single battery
or
±1V
to
±5V
dual battery user and offers the popular industry standard
single operational amplifier pin configuration.
Several important characteristics of the device make application easier
to implement at those voltages. First, the operational amplifier can
operate with rail to rail input and output voltages. This means the signal
input voltage and output voltage can be close to or equal to the positive
and negative supply voltages. This feature allows numerous analog
serial stages and flexibility in input signal bias levels. Second, the 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
400KHz, a slew rate of 0.17V/µs, low offset voltage and temperature
drift, make the ALD1706A/ALD1706B/ALD1706/ALD1706G a versatile,
micropower operational amplifier.
The ALD1706A/ALD1706B/ALD1706/ALD1706G, designed and
fabricated with silicon gate CMOS technology, offers 0.1 pA typical input
bias current. 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.
