GENERAL DESCRIPTION
The ALD1712A/ALD1712B/ALD1712 is a monolithic precision opera-
tional amplifier intended primarily for a wide range of analog applications
in +5V single power supply and ±5V dual power supply systems as well
as +5V to +10V 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 ALD1712A/ALD1712B/ALD1712 has an input stage that operates to
+300mV above and -300mV below the supply voltages with no adverse
effects and/or phase reversals. It 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. Second, the device was designed to
accommodate mixed applications where digital and analog circuits may
work off the same 5V power supply. Third, the output stage can drive up
to 400pF capacitive, and 1KΩ 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/µs, low power dissipation, low offset voltage
and temperature drift, make the ALD1712A/ALD1712B/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 5µV/°C which eliminates many trim or temperature compensation
circuits. For precision applications, the ALD1712A/ALD1712B/ALD1712
is designed to settle to 0.01% in 8µs. The unique characteristics at input
and output are modeled in an available macromodel. Additionally, robust
design and rigorous screening make this device especially suitable for
operation in temperature-extreme environments and rugged conditions.
