GENERAL DESCRIPTION

The ALD1702A/ALD1702B/ALD1702/ALD1703 is a 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 +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.
