GENERAL DESCRIPTION
The ALD4702A/ALD4702B/ALD4702 is a quad monolithic precision
CMOS rail-to-rail operational amplifier intended for a broad range of
analog applications using ±2.5V to ±5V dual power supply systems, as
well as +4V to +10V 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 6mA maximum at 5V
supply voltage. It is manufactured with Advanced Linear Devices'
enhanced ACMOS silicon gate CMOS process.
The ALD4702A/ALD4702B/ALD4702 is designed to offer a trade-off of
performance parameters providing a wide range of desired
specifications. It has been developed specifically with the +5V single
supply or ±2.5V dual supply user andoffers the popular industry pin
configuration of LM324 and ICL7641 types.
Several important characteristics of the device make many applications
easy to implement for these supply voltages. First, the operational
amplifier can operate with rail to rail input and output voltages. This
feature allows numerous analog serial stages to be implemented
without losing operating voltage margin. Second, the device was
designed to accommodate mixed applications where digital and
analog circuits may work off the same 5V power supply. Third, the
output stage can drive up to 400pF capacitive and 5KΩ resistive loads
in non-inverting unity gain connection and double the capacitance in
the inverting unity gain mode.
These features, coupled with extremely low input currents, high
voltage gain, useful bandwidth of 1.5MHz, a slew rate of 2.1V/µs, low
power dissipation, low offset voltage and temperature drift, make the
ALD4702A/ALD4702B/ALD4702 a truly versatile, user friendly,
operational amplifier.
The ALD4702A/ALD4702B/ALD4702 is designed and fabricated with
silicon gate CMOS technology, and offers 1pA typical input bias
current. On-chip offset voltage trimming allows the device to be used
without nulling in most applications. The device offers typical offset
drift of less than 7µV/°C which eliminates many trim or temperature
compensation circuits. For precision applications, the ALD4702A/
ALD4702B/ALD4702 is designed to settle to 0.01% in 8µs. Additionally,
robust design and rigorous screening make this device especially
suitable for operation in temperature-extreme environments and rugged
conditions.
