GENERAL DESCRIPTION

The ALD4701 is a quad monolithic CMOS micropower high slew rate

operational amplifier intended for a broad range of analog applications

using 1V to 6V dual power supply systems, as well as +2V to +12V

battery operated systems. All device characteristics are specified for +5V

single supply or 2.5V dual supply systems. Total supply current for all four

operational amplifiers is 1mA maximum at 5V supply voltage. It is

manufactured with Advanced Linear Devices' enhanced ACMOS silicon

gate CMOS process.

The ALD4701 is designed to offer a trade-off of performance parameters

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

industry standard pin configuration of LM324 types and ICL 7641 types.

The ALD4701 has been developed specifically for the +5V single supply or

device make application easier to implement at these voltages.

First, each operational amplifier can operate with rail to rail input and output

voltages. This means the signal input voltage and output voltage can be

equal to or near to the positive and negative supply voltages. This feature

allows numerous analog serial stages and flexibility in input signal bias

levels. Secondly, each device was designed to accommodate mixed

applications where digital and analog circuits may operate off the same

power supply or battery. Thirdly, the output stage can typically drive up to

50pF capacitive and 10K

These features, combined with extremely low input currents, high open

loop voltage gain of 100V/mV, useful bandwidth of 700KHz, a slew rate of

0.7V/ s, low power dissipation of 5mW, low offset voltage and temperature

drift, make the ALD4701 a versatile, micropower quad operational amplifier.

The ALD4701, designed and fabricated with silicon gate CMOS technology,

offers 1pA typical input bias current. Due to low voltage and low power

operation, reliability and operating characteristics, such as input bias

currents and warm up time, are greatly improved.
