ALD2704
GENERAL DESCRIPTION
The 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 ALD2704 ap-
proaches 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
±
6V power supplies are being used. The ALD2704 offers high slew rate
of 5V/
μ
s. 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 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 1.5K
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 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 2
μ
s. 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.
