GENERAL DESCRIPTION

The ALD4706A/ALD4706B/ALD4706 is a quad monolithic CMOS ultra

micropower high slew-rate operational amplifier intended for a broad

range of analog applications using ±1V to ±5V dual power supply

systems, as well as +2V to +10V 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 200µA

maximum at 5V supply voltage. It is manufactured with Advanced Linear

Devices' enhanced ACMOS silicon gate CMOS process.

The ALD4706A/ALD4706B/ALD4706 is designed to offer a trade-off of

performance parameters providing a wide range of desired specifications.

It has been developed specifically for the +5V single supply or ±1V to

±5V dual supply user and offers the popular industry standard pin

configuration of LM324 types and ICL7641 types.

Several important characteristics of the 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. Second, each

device was designed to accommodate mixed applications where digital

and analog circuits may operate off the same power supply or battery.

Third, the output stage can typically drive up to 25pF capacitive and

20KΩ resistive loads. These features, combined with extremely low

input currents, high open loop voltage gain of 100V/mV, useful bandwidth

of 200KHz, a slew rate of 0.17V/µs, low power dissipation of 0.5mW,

low offset voltage and temperature drift, make the ALD4706A/ALD4706B/

ALD4706 a versatile, ultra micropower quad operational amplifier.

The ALD4706A/ALD4706B/ALD4706, designed and fabricated with

silicon gate CMOS technology, offers 0.1pA 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. Additionally, robust design and rigorous screening make this

device especially suitable for operation in temperature-extreme

environments and rugged conditions.
