GENERAL DESCRIPTION
The ALD1704A/ALD1704B/ALD1704/ALD1704G 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 ±5V power supplies are being used. It
offers high slew rate of 5V/µs at low operating power of 30mW. Since the
ALD1704A/ALD1704B/ALD1704/ALD1704G is designed and manufac-
tured 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 ALD1704A/ALD1704B/
ALD1704/ALD1704G 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 1.5KΩ 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 complementary 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 2µs. 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. Additionally, robust design and rigorous screening
make this device especially suitable for operation in temperature-ex-
treme environments and rugged conditions.
