ALD4702
QUAD 5V RAIL-TO-RAIL PRECISION OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
The ALD4702 is a quad monolithic precision CMOS rail-to-rail
operational amplifier intended for a broad range of analog applications
using
鹵2.5V
to
鹵6V
dual power supply systems, as well as +4V to
+12V battery operated systems. All device characteristics are
specified for +5V single supply or
鹵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 ALD4702 is designed to offer a trade-off of performance
parameters providing a wide range of desired specifications. It offers
the popular industry pin configuration of LM324 and ICL7641 types.
The ALD4702 has been developed specifically with the +5V single
supply or
鹵2.5V
dual supply user. 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. Secondly, the device was designed to accommodate
mixed applications where digital and analog circuits may work off the
same 5V power supply. Thirdly, the output stage can drive up to
400pF capacitive and 5K鈩?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/碌s, low
power dissipation, low offset voltage and temperature drift, make the
ALD4702 a truly versatile, user friendly, operational amplifier.
The 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 7碌V/
擄C
which eliminates many trim or temperature compensation circuits.
For precision applications, the ALD4702 is designed to settle to
0.01% in 8碌s.
