GENERAL DESCRIPTION

The ALD1706A/ALD1706B/ALD1706/ALD1706G is a monolithic CMOS

ultra micropower high slew-rate, high performance 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. Supply current is 40μA maximum at 5V supply

voltage. It is manufactured with Advanced Linear Devices' enhanced

ACMOS silicon gate CMOS process.

The ALD1706A/ALD1706B/ALD1706/ALD1706G is designed to offer high

performance for a wide range of applications requiring very low power

dissipation. It has been developed specifically for the +5V single battery

or ±1V to ±5V dual battery user and offers the popular industry standard

single operational amplifier pin configuration.

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. Second, the 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

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

drift, make the ALD1706A/ALD1706B/ALD1706/ALD1706G a versatile,

micropower operational amplifier.

The ALD1706A/ALD1706B/ALD1706/ALD1706G, designed and

fabricated with silicon gate CMOS technology, offers 0.1 pA typical input

bias current. On chip offset voltage trimming allows the device to be

used without nulling in most applications. Additionally, robust design

and rigorous screening make this device especially suitable for operation

in temperature-extreme environments and rugged conditions.
