The Maxim ICL7116 and ICL7117 are 3½ digit monolithic analog-to-digital converters. They differ from the Maxim ICL7106 and ICL7107 in that the ICL7116 and ICL7117 have a Hold pin, which makes it possible to hold or “freeze” a reading. These integrating ADCs have very high input impedances and directly drive LCD (ICL7116) and LED (ICL7117) displays.Versatility and accuracy are inherent features of these converters. The dual-slope conversion technique automatically rejects interference signals common in industrial environments. The true differential input is particularly useful when making ratiometric measurements (ohms or bridge transducers). Maxim has added a zero-integrator phase to the ICL7116 and ICL7117, eliminating overrange hangover and hysteresis effects. Finally, these devices offer high accuracy by lowering rollover error to less than one count and zero reading drift to less than 1µV/°C.ApplicationsConductanceCurrentMaterial ThicknessPressureResistanceSpeedTemperatureVoltage

The ICL761X–ICL764X family of monolithic CMOS op amps combine ultra-low input current with low-power operation over a wide supply voltage range. With pinselectable quiescent currents of 10µA, 100µA, or 1000µA per amplifier, these op amps will operate from ±1V to ±8V power supplies, or from single supplies from 2V to 16V. The CMOS outputs swing to within millivolts of the supply voltages.The ultra-low bias current of 1pA makes this family of op amps ideal for long time constant integrators, picoammeters, low droop rate sample/hold amplifiers and other applications where input bias and offset currents are critical. A low noise current of 0.01pA and an input impedance of 1012Ω ensure optimum performance with very high source impedances in such applications as pH meters and photodiode amplifiers.ApplicationsBattery-Powered InstrumentsHearing Aids and Microphone AmplifiersLong-Time Constant IntegratorsLow Droop Rate Sample/Hold AmplifiersLow-Frequency Active FiltersLow-Leakage AmplifiersPicoammeters
