The TLC2652 and TLC2652A are high-precision chopper-stabilized operational amplifiers using Texas Instruments Advanced LinCMOS(TM) pro-cess. 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 sin 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 forlow-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 of10 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. Two external capacitors are required for operation of the device; however, the on-chip chopper-control circuitryis transparent to the user. On devices in the 14-pin and 20-pin packages, the control circuitry is made accessible to allow the user the option of controlling the clock frequency with an external frequency source. In addition, the clock threshold level of the TLC2652 and TLC2652A requires no level shifting when used in the single-supply configuration with a normal CMOS or TTL clock input.
