GENERAL DESCRIPTION

The ALD1736A/ALD1736 is a precision low-cost ultra micropower high

slew-rate high performance monolithic CMOS 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. Typical supply current is 20µA at 5V

enhanced EPAD® silicon gate CMOS process.

The ALD1736A/ALD1736 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

ALD1736A/ALD1736 a versatile, ultra micropower operational ampli-

fier.

The ALD1736A/ALD1736, designed and fabricated with silicon gate

CMOS technology, offers on-chip offset voltage trimming, allowing the

device to be used without nulling in most applications.

It is also

designed to offer tolerance to over-voltage input spikes of 300mV

beyond supply rails, high open loop voltage gain, and robust operation

screening make this device especially suitable for operation in tempera-

ture-extreme environments and rugged conditions.
