GENERAL DESCRIPTION
The ALD4701A/ALD4701B/ALD4701 is a quad 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. Total supply
current for all four operational amplifiers is 1mA maximum at 5V supply
voltage. It is manufactured with Advanced Linear Devices' enhanced
ACMOS silicon gate CMOS process.
The ALD4701A/ALD4701B/ALD4701 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 LM324 types and ICL7641 types.
Several important characteristics of the device make application easier to
implement at these voltages. First, each 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 or near to the positive and
negative supply voltages. This feature allows numerous analog serial
stages and flexibility in input signal bias levels. Second, each 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 10K 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/s, low power dissipation of 5mW, low offset voltage and temperature
drift, make the ALD4701A/ALD4701B/ALD4701 a versatile, micropower
quad operational amplifier.
The ALD4701A/ALD4701B/ALD4701, designed and fabricated with silicon
gate CMOS technology, offers 1pA typical input bias current. Due to low
voltage and low power operation, reliability and operating characteristics,
such as input bias currents and warm up time, are greatly improved.
Additionally, robust design and rigorous screening make this device
especially suitable for operation in temperature-extreme environments and
rugged conditions.
