QUAD MICROPOWER RAIL-TO-RAIL CMOS OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
The ALD4701 is a quad 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. 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 ALD4701 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 LM324 types and ICL 7641 types.
The ALD4701 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 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. Secondly, each 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 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 5mW, low offset voltage and temperature
drift, make the ALD4701 a versatile, micropower quad operational amplifier.
The 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.
