说明

The ICL7652 is a precision chopper-stabilized operational amplifier manufactured using Texas Instruments Advanced LinCMOS™ process. This process, in conjunction with unique chopper-stabilization circuitry, produces an operational amplifier whose performance matches or exceeds that of similar devices available today.

Chopper stabilization techniques make possible extremely high dc precision by continuously nulling input offset voltage even with variations in temperature, time, common-mode voltage, and supply voltage. Additionally, low-frequency noise voltage is significantly reduced. This precision, coupled with the extremely high input impedance of the CMOS input stage, makes the ICL7652 an ideal choice for low-level signal-processing applications such as strain gauges, thermocouples, and other transducer amplifiers.
