Description : Advanced LinCMOS PRECISION CHOPPER-STABILIZED OPERATIONAL AMPLIFIERS View

description
The TLC2652 and TLC2652A are high-PRECISION CHOPPER-STABILIZED OPERATIONAL AMPLIFIERs using Texas Instruments Advanced LinCMOS process. This process in conjunction WITH unique CHOPPER-stabilization circuitry produces opera tional AMPLIFIERs 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 during variation in temperature, time, common-mode voltage, and power supply voltage. In addition, low-frequency noise voltage is significantly reduced. This high PRECISION, coupled WITH the extremely high input impedance of the CMOS input stage, makes the TLC2652 and TLC2652A an ideal choice for low-level signal processing applications such as strain gauges, thermocouples, and other transducer AMPLIFIERs. For applications that require extremely low noise and higher usable bandwidth, use the TLC2654 or TLC2654A device, which has a chopping frequency of 10 kHz.
The TLC2652 and TLC2652A input common-mode range includes the negative rail, thereby providing superior performance in either single-supply or split-supply applications, even at power supply voltage levels as low as ±1.9 V.
