GENERAL DESCRIPTION
The ALD1704 is a CMOS 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.
This device is designed as an alternative to the popular JFET input
operational amplifiers in applications where lower operating voltages, such
as 9V battery or
±3.25V to±6V power supplies are being used. It offers high
slew rate of 5V/
s at low operating power of 30mW. Since the ALD1704
is designed and manufactured with Advanced Linear Devices' standard
enhanced ACMOS silicon gate CMOS process, it also offers low unit cost
and exceptional reliability.
The rail-to-rail input and output feature of the ALD1704 allows a lower
operating supply voltage for a given signal voltage range 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
4000 pF at a gain of 5. Short circuit protection to either ground or the power
supply rails is at approximately 15mA clamp current. Due to complemen-
tary output stage design, the output can both source and sink 10mA into
a load with symmetrical drive and is ideally suited for applications where
push-pull voltage drive is desired.
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
s. For large signal buffer applications, the
operational amplifier can function as an ultra high 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.
