GENERAL DESCRIPTION
The ALD2724E/ALD2724 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 ALD2724E/ALD2724
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 ALD2724E/ALD2724 offers
high slew rate of 5.0V/
s.
The rail-to-rail input and output feature of the ALD2724E/ALD2724
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 1.5K
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 applica-
tions where push-pull voltage drive is desired.
