GENERAL DESCRIPTION

The ALD1701A/ALD1701B/ALD1701/ALD1701G is a monolithic CMOS

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. Supply current is 250μA maximum at 5V supply voltage. It is

manufactured with Advanced Linear Devices' enhanced ACMOS silicon

gate CMOS process.

The ALD1701A/ALD1701B/ALD1701/ALD1701G 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 μA741 and ICL7611 types.

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. 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 50pF capacitive and 10KΩ 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

temperature drift, make the ALD1701 a versatile, micropower operational

amplifier.

The ALD1701A/ALD1701B/ALD1701/ALD1701G, designed and fabricated

with silicon gate CMOS technology, offers 1pA 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.
