19-0942; Rev 3; 5/10Single/Dual/Triple/Quad Operational AmplifiersGeneral DescriptionFeaturesThe ICL761X–ICL764X family of monolithic CMOS opamps combine ultra-low input current with low-poweroPin-for-Pin Second Sourceoperation over a wide supply voltage range. With pin-o1pA Typical Bias Current—4nA (max) at +125°Cselectable quiescent currents of 10µA, 100µA, oro±1V to ±8V Wide Supply Voltage Range1000µA per amplifier, these op amps will operate from±1V to ±8V power supplies, or from single suppliesoIndustry-Standard Pinouts

from 2V to 16V. The CMOS outputs swing to within milli-o

Programmable Quiescent Currents of 10µA,volts of the supply voltages.

100µA, and 1000µA

The ultra-low bias current of 1pA makes this family ofoMonolithic, Low-Power CMOS Design

op amps ideal for long time constant integrators,picoammeters, low droop rate sample/hold amplifiersand other applications where input bias and offset cur-rents are critical. A low noise current of 0.01pA√Hzandan input impedance of 1012Ωensure optimum perfor-mance with very high source impedances in suchapplications as pH meters and photodiode amplifiers.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functionaloperation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure toabsolute maximum rating conditions for extended periods may affect device reliability.Note 1:Long-term offset voltage stability will be degraded if large input differential voltages are applied for long periods of time.Note 2:The outputs may be shorted to ground or to either supply for VSUPP≤10V. Care must be taken to insure that the dissipation

rating is not exceeded.

ICL761X–ICL764XSingle/Dual/Triple/Quad Operational AmplifiersICL761X–ICL764XSingle-Supply OperationThe ICL7611 family will operate from a single 2V to 16Vpower supply. The common-mode voltage range of thestandard amplifier types when operated from a singlesupply is 1.0V to (V+ - 0.6V) at 10µA IQ. At 100µA IQ,the CMVR is 1.0V to (V+ - 0.8V), and at 1mA IQ, theCMVR is 1.3V to (V+ - 1.3V). If this CMVR range isinsufficient, use the ICL7612, whose CMVR includesboth ground and V+, or the ICL7616, whose CMVRincludes ground.

A convenient way to generate a psuedo-ground at V+/2is to use one op amp of a quad to buffer a V+/2 voltagefrom a high-impedance resistive divider.

Low-Voltage OperationOperation at VSUPP= ±1.0V is only guaranteed at IQ=10µA. Output swings to within a few millivolts of thesupply rails are achievable for RL(> or =) 1MΩ.Guaranteed input CMVR is ±0.6V minimum and typical-ly +0.9V to -0.7V at VSUPP= ±1.0V. For applicationswhere greater common-mode range is desirable, seethe description of ICL7612 and ICL7616 above.

Applications InformationNote that in no case is IQ shown. The value of IQ mustbe chosen by the designer with regard to frequencyresponse and power dissipation.
