ULTRA MICROPOWER RAIL-TO-RAIL CMOS OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
The ALD1706 is a monolithic CMOS ultra micropower high slew-rate, high
performance 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 40µA
maximum at 5V supply voltage. It is manufactured with Advanced Linear
Devices' enhanced ACMOS silicon gate CMOS process.
The ALD1706 is designed to offer high performance for a wide range of
applications requiring very low power dissipation. It offers the popular
industry standard single operational amplifier pin configuration.
The ALD1706 has been developed specifically for the +5V single battery
or ±1V to ±6V dual battery user. 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.
Secondly, the 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 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 ALD1706 a versatile, micropower operational amplifier.
The ALD1706, designed and fabricated with silicon gate CMOS techno-
logy, offers 0.1pA typical input bias current. On chip offset voltage trimming
allows the device to be used without nulling in most applications.
