GENERAL DESCRIPTION
The ALD1712 is a monolithic precision operational amplifier intended
primarily for a wide range of analog applications in +5V single power supply
and
±
5V dual power supply systems as well as +6V to 12V battery operated
systems. All device characteristics are specified for +5V single supply or
±
2.5V dual supply systems. It is manufactured with Advanced Linear
Devices' enhanced ACMOS silicon gate CMOS process and is available as
a standard cell in ALD's ASIC "Function-Specific" library.
The device has an input stage that operates to +300mV above and -300mV
below the supply voltages with no adverse effects and/or phase reversals.
The ALD1712 has been developed specifically with the 5V single supply or
±
2.5V dual supply user in mind. Several important characteristics of the
device make many applications easy to implement for these supply
voltages. First, the operational amplifier can operate with rail-to-rail input
and output voltages. This feature allows numerous analog serial stages to
be implemented without losing operating voltage margin. Secondly, the
device was designed to accommodate mixed applications where digital
and analog circuits may work off the same 5V power supply. Thirdly, the
output stage can drive up to 400pF capacitive, and 1K
resistive loads in
non-inverting unity gain connection, and up to 4000pF at a gain of 5. These
features, coupled with extremely low input currents, high voltage gain,
useful bandwidth of 1.5MHz, slew rate of 2.1V/
μ
s, low power dissipation,
low offset voltage and temperature drift, make the ALD1712 a truly
versatile, user friendly, operational amplifier.
On-chip offset voltage trimming allows the device to be used without nulling
in most applications. The device offers typical offset drift of less than 5
μ
V/
°
C which eliminates many trim or temperature compensation circuits. For
precision applications, the 1712 is designed to settle to 0.01% in 8
μ
s. The
unique characteristics at input and output are modeled in an available
macromodel.
