ALD4702  
QUAD 5V RAIL-TO-RAIL PRECISION OPERATIONAL AMPLIFIER  
GENERAL DESCRIPTION  
FEATURES  
The ALD4702A/ALD4702B/ALD4702 is a quad monolithic precision  
CMOS rail-to-rail operational amplifier intended for a broad range of  
analogapplicationsusing±2.5Vto±5Vdualpowersupplysystems, as  
wellas+4Vto+10Vbatteryoperatedsystems. Alldevicecharacteristics  
arespecifiedfor+5Vsinglesupplyor±2.5Vdualsupplysystems. 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.  
• Rail-to-rail input and output voltage ranges  
• Symmetrical push-pull class AB output drivers  
• All parameters specified for +5V single supply  
or ±2.5V dual supply systems  
• Inputscanextendbeyondsupplyrailsby300mV  
• Outputs settle to 2mV of supply rails  
• High load capacitance capability up to 4000pF  
• No frequency compensation required --  
unity gain stable  
TheALD4702A/ALD4702B/ALD4702isdesignedtoofferatrade-offof  
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.  
• Extremely low input bias currents --  
1.0pA typical  
• Ideal for high source impedance applications  
• Dual power supply ±2.5V to ±5.0V operation  
• Single power supply +5V to +10V operation  
• High voltage gain-typically 85V/mV @ ±2.5V  
and 250V/mV @ ±5.0V  
• Drive as low as 2KΩ load with 5mA drive current  
• Output short circuit protected  
• Unity gain bandwidth of 1.5MHz  
• Slew rate of 1.9V/µs  
• Low power dissipation  
Severalimportantcharacteristicsofthedevicemakemanyapplications  
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.  
• Suitable for rugged, temperature-extreme  
environments  
APPLICATIONS  
• Voltage amplifier  
• Voltage follower/buffer  
• Charge integrator  
• Photodiode amplifier  
• Data acquisition systems  
• High performance portable instruments  
• Signal conditioning circuits  
• Sensor and transducer amplifiers  
• Low leakage amplifiers  
• Active filters  
• Sample/Hold amplifier  
• Picoammeter  
• Current to voltage convert  
• Coaxial cable driver  
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/ALD4702isdesignedtosettleto0.01%in8µs. Additionally,  
robust design and rigorous screening make this device especially  
suitableforoperationintemperature-extremeenvironmentsandrugged  
conditions.
