ALD4704  
QUAD RAIL-TO-RAIL CMOS OPERATIONAL AMPLIFIER  
GENERAL DESCRIPTION  
FEATURES  
• Rail-to-rail input and output voltage ranges  
• 5.0V/µs slew rate  
• Symmetrical push-pull output drive  
• Inputs can extend beyond supply rails by  
300mV  
• Outputs settle to 2mV of supply rails  
• High capacitive load capability -- up to  
4000pF  
The ALD4704 is a quad CMOS monolithic operational amplifier with  
MOSFET input that has rail-to-rail input and output voltage ranges. The  
+
input voltage can be beyond positive power supply voltage V or the  
-
negative power supply voltage V by up to 300mV. The output voltage  
swings to within 60mV of either positive or negative power supply voltages  
at rated load.  
With high impedance load, the output voltage approaches to within 1mV  
of the power supply rails. This device is designed as an alternative to the  
popular J-FET input operational amplifiers in applications where lower  
operating voltages, such as 9V battery or ±3.25V to ±6V power supplies  
are being used. It offers high slew rate of 5V/µs at low operating power.  
The ALD4704 is designed and manufactured with Advanced Linear  
Devices' standard enhanced ACMOS silicon gate CMOS process for low  
unit cost and exceptional reliability.  
• No frequency compensation required –  
unity gain stable  
• Extremely low input bias currents -- 1.0pA  
typical (20pA max.)  
• Ideal for high source impedance applica-  
tions  
• High voltage gain -- typically 100V/mV  
• Output short circuit protected  
• Unity gain bandwidth of 2.1MHz  
The rail-to-rail input and output feature of the ALD4704 expand signal  
voltage range for a given operating supply voltage and allow numerous  
analog serial stages to be implemented without losing operating voltage  
margin. The output stage is designed to drive up to 10mA into 400pF  
capacitive and 1.5KΩ resistive loads at unity gain and up to 4000pF at a  
gain of 5. Short circuit protection to either ground or the power supply rails  
is at approximately 15mA clamp current. The output can both source and  
sink 10mA into a load with symmetrical drive and is ideally suited for  
applications where push-pull voltage drive is desired.  
APPLICATIONS  
• Voltage amplifier  
• Voltage follower/buffer  
• Charge integrator  
• Photodiode amplifier  
• Data acquisition systems  
• High performance portable  
instruments  
• Signal conditioning circuits  
• Low leakage amplifiers  
• Active filters  
• Sample/Hold amplifier  
• Picoammeter  
• Current to voltage converter  
• Coaxial cable driver  
• Capacitive sensor amplifier  
• Piezoelectric transducer amplifier  
Foreachoftheoperationalamplifier, theoffsetvoltage is trimmedon-chip  
to eliminate the need for external nulling in many applications. For  
precision applications, the output is designed to settle to 0.1% in 2µs. For  
large signal buffer applications, the operational amplifier can function as  
an ultrahigh input impedance voltage follower/buffer that allows input  
andoutput voltageswings from positivetonegativesupplyvoltages. This  
featureisintendedtogreatlysimplifysystemsdesignand eliminatehigher  
voltage power supplies in many applications.
