The TLC2652ACP is a single high-precision chopper-stabilized Operational Amplifier using Texas Instruments Advanced LinCMOS? process. This process, in conjunction with unique chopper-stabilization circuitry, produces 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 during variations 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 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 TLC2654A device, which has a chopping frequency of 10kHz.
