QUAD ULTRA MICROPOWER RAIL-TO-RAIL CMOS OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
The ALD4706 is a quad monolithic CMOS ultra 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 four
operational amplifiers is 200µA maximum at 5V supply voltage. It is
manufactured with Advanced Linear Devices' enhanced ACMOS silicon
gate CMOS process.
The ALD4706 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 ICL7641 types.
The ALD4706 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 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 200KHz, a slew rate of 0.17V/µs, low power dissipation of 0.5mW, low
offset voltage and temperature drift, make the ALD4706 a versatile, ultra
micropower quad operational amplifier.
The ALD4706, designed and fabricated with silicon gate CMOS techno-
logy, offers 0.1pA 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.
