TLC2654CN

Product Summary

The TLC2654CN is a low-noise chopper-stabilized operational amplifier using the Advanced LinCMOSE process. Combining this process with chopper-stabilization circuitry makes excellent dc precision possible. In addition, circuit techniques are added that give the TLC2654CN noise performance unsurpassed by similar devices. 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 TLC2654CN provides excellent noise performance in a frequency spectrum from near dc to 10 kHz.
