GENERAL DESCRIPTION
The ALD2704A/ALD2704B/ALD2704 is a dual monolithic operational
amplifier with MOSFET input that has rail-to-rail input and output voltage
ranges. The input voltage range and output voltage range are very close
to the positive and negative power supply voltages. Typically the input
voltage can be beyond positive power supply voltage V
+
or the negative
power supply voltage V
-
by up to 300mV. The output voltage swings to
within 60mV of either positive or negative power supply voltages at rated
load.
With high impedance load, the output voltage of the ALD2704A/ALD2704B/
ALD2704 approaches within 1mV of the power supply rails. This device
is designed as an alternative to the popular J-FET input operational
amplifier in applications where lower operating voltages, such as 9V
battery or ±3.25V to ±5V power supplies are being used. The ALD2704A/
ALD2704B/ALD2704 offers high slew rate of 5V/µs. It is designed and
manufactured with Advanced Linear Devices' standard enhanced ACMOS
silicon gate CMOS process, and it offers low unit cost and exceptional
reliability.
The rail-to-rail input and output feature of the ALD2704A/ALD2704B/
ALD2704 expands signal voltage range for a given operating supply
voltage and allows numerous analog serial stages to be implemented
without losing operating voltage margin. The output stage is designed to
drive up to 10mA into 400pF capacitive and 1.5KΩ resistive loads at unity
gain and up to 4000pF at a gain of 5. Short circuit protection to either
ground or the power supply rails is at approximately 15mA clamp current.
Due to complementary output stage design, the output can source and
sink 10mA into a load with symmetrical drive and is ideally suited for
applications where push-pull voltage drive is desired.
For each of the operational amplifier, the offset voltage is trimmed on-chip
to eliminate the need for external nulling in many applications. For
precision applications, the output is designed to settle to 0.1% in 2µs. In
large signal buffer applications, the operational amplifier can function as
an ultrahigh input impedance voltage follower /buffer that allows input and
output voltage swings from positive to negative supply voltages. This
feature is intended to greatly simplify systems design and eliminate higher
voltage power supplies in many applications. Additionally, robust design
and rigorous screening make this device especially suitable for operation
in temperature-extreme environments and rugged conditions.
