说明

The TLC2654 and TLC2654A are low-noise chopper-stabilized operational amplifiers using the Advanced LinCMOS^TM process. Combining this process with chopper-stabilization circuitry makes excellent dc precision possible. In addition, circuit techniques are added that give the TLC2654 and TLC2654A superior noise performance.

Chopper-stabilization techniques provide for extremely high dc precision by continuously nulling input offset voltage even during variations in temperature, time, common-mode voltage, and power-supply voltage. The high chopping frequency of the TLC2654 and TLC2654A (see Figure 1) provides excellent noise performance in a frequency spectrum from near dc to 10 kHz. In addition, intermodulation or aliasing error is eliminated from frequencies up to 5 kHz.
