ALD4704A/ALD4704B
ALD4704
QUAD RAIL-TO-RAIL CMOS OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
The ALD4704A/ALD4704B/ALD4704 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 ALD4704A/
ALD4704B/ALD4704 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
ALD4704A/ALD4704B/ALD4704 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 ALD4704A/ALD4704B/
ALD4704 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.
