GENERAL DESCRIPTION
The ALD1702A/ALD1702B/ALD1702/ALD1703 is a monolithic 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 +4V 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.
The ALD1702A/ALD1702B/ALD1702/ALD1703 is designed to offer a
balanced trade-off of performance parameters providing a wide range of
desired specifications. It has been developed specifically with the 5V
single supply or ±2.5 dual supply user in mind and offers the industry
pin configuration of µA741 and ICL7611 types.
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 5KΩ resistive loads in non-inverting unity
gain connection and double the capacitance in the inverting unity gain
mode.
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 ALD1702A/
ALD1702B/ALD1702/ALD1703 a truly versatile, user friendly, operational
amplifier.
The ALD1702A/ALD1702B/ALD1702/ALD1703 is designed and
fabricated with silicon gate CMOS technology, and offers 1pA typical
input bias current. 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 7µV/°C which eliminates many trim or temperature
compensation circuits. For precision applications, it is designed to settle
to 0.01% in 8µs. Additionally, robust design and rigorous screening make
this device especially suitable for operation in temperature-extreme
environments and rugged conditions.
