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 5K

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/ s, low power

dissipation, low offset voltage and temperature drift, make the ALD1702/

ALD1703 a truly versatile, user friendly, operational amplifier.

The 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 7 V/ C which

eliminates many trim or temperature compensation circuits. For precision

applications, the ALD1702 is designed to settle to 0.01% in 8 s.

ORDERING INFORMATION

GENERAL DESCRIPTION

The 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 +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.

The device is designed to offer a balanced trade-off of performance

parameters providing a wide range of desired specifications. It offers the

industry pin configuration of A741 and ICL7611 types.
