GENERAL DESCRIPTION
The ALD4706A/ALD4706B/ALD4706 is a quad monolithic CMOS ultra
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. Total supply current for four operational amplifiers is 200µA
maximum at 5V supply voltage. It is manufactured with Advanced Linear
Devices' enhanced ACMOS silicon gate CMOS process.
The ALD4706A/ALD4706B/ALD4706 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 of LM324 types and ICL7641 types.
Several important characteristics of the device make application easier
to implement at these 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 or near 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 0.17V/µs, low power dissipation of 0.5mW,
low offset voltage and temperature drift, make the ALD4706A/ALD4706B/
ALD4706 a versatile, ultra micropower quad operational amplifier.
The ALD4706A/ALD4706B/ALD4706, designed and fabricated with
silicon gate CMOS technology, offers 0.1pA typical input bias current.
Due to low voltage and low power operation, reliability and operating
characteristics, such as input bias currents and warm up time, are greatly
improved. Additionally, robust design and rigorous screening make this
device especially suitable for operation in temperature-extreme
environments and rugged conditions.

... To maintain compatibility with other operational amplifiers, this switching point has been selected to be about 1.5V below the positive supply voltage. Since offset voltage trimming on the ALD4706A/ ALD4706B/ALD4706 is made when the input voltage is symmetrical to the supply voltages, this internal switching does not affect a large variety of applications such as an inverting amplifier or non-inverting amplifier with a gain larger than 2 ...
