ALD2702
DUAL 5V RAIL-TO-RAIL PRECISION OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
The ALD2702 is a dual monolithic 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 +4V to +12V battery operated
systems. All device characteristics are specified for +5V single supply or
±2.5V dual supply systems. 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. It offers popular industry pin configuration.
www.DataSheetT4Uhe.coAmLD2702 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 5Kresistive 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, a slew rate of 1.9V/µs, low power
dissipation, low offset voltage and temperature drift, make the ALD2702 a
truly versatile, user friendly, operational amplifier.
The ALD2702 is designed and fabricated with silicon gate CMOS technology,
and offers less than 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,
the ALD2702 is designed to settle to 0.01% in 8µs.
