GENERAL DESCRIPTION

The ALD1701 is a 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. Supply current is 250µA maximum at 5V

supply voltage. It is manufactured with Advanced Linear Devices' en-

hanced ACMOS silicon gate CMOS process.

The ALD1701 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

µA741 and ICL7611 types.

The ALD1701 has been developed specifically for the +5V single supply or

±1V to ±6V dual supply 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

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 50pF capacitive

and 10K

Ω resistive loads.

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/

µs, low power dissipation of 0.5mW, low offset voltage and tempera-

ture drift, make the ALD1701 a versatile, micropower operational amplifier.

The ALD1701, designed and fabricated with silicon gate CMOS techno-

logy, offers 1pA typical input bias current. On chip offset voltage trimming

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