GENERAL DESCRIPTION

The ALD1706 is a monolithic CMOS ultra micropower high slew-rate, high

performance 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. Supply current is 40 A

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

Devices' enhanced ACMOS silicon gate CMOS process.

The ALD1706 is designed to offer high performance for a wide range of

applications requiring very low power dissipation.

industry standard single operational amplifier pin configuration.

The ALD1706 has been developed specifically for the +5V single battery

or 1V to 6V dual battery user. Several important characteristics of the

device make application easier to implement at those voltages. First, the

operational amplifier can operate with rail to rail input and output voltages.

This means the signal input voltage and output voltage can be close to or

equal to the positive and negative supply voltages. This feature allows

numerous analog serial stages and flexibility in input signal bias levels.

Secondly, the 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 25pF capacitive

and 20K

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

of 400KHz, a slew rate of 0.17V/ s, low offset voltage and temperature drift,

make the ALD1706 a versatile, micropower operational amplifier.

The ALD1706, designed and fabricated with silicon gate CMOS techno-

logy, offers 0.1 pA typical input bias current. On chip offset voltage trimming

allows the device to be used without nulling in most applications.
