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 fabri-
cated 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.
