GENERAL DESCRIPTION

The ALD4702 is a quad monolithic precision CMOS rail-to-rail

operational amplifier intended for a broad range of analog applications

using 2.5V to 6V 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. Total

supply current for four operational amplifiers is 6mA maximum at 5V

supply voltage. It is manufactured with Advanced Linear Devices'

enhanced ACMOS silicon gate CMOS process.

The ALD4702 is designed to offer a trade-off of performance

parameters providing a wide range of desired specifications. It offers

the popular industry pin configuration of LM324 and ICL7641 types.

The ALD4702 has been developed specifically with the +5V single

supply or 2.5V dual supply user. 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 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, a slew rate of 2.1V/ s, low

power dissipation, low offset voltage and temperature drift, make the

ALD4702 a truly versatile, user friendly, operational amplifier.

The ALD4702 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/

For precision applications, the ALD4702 is designed to settle to

0.01% in 8 s.
