TLC2654CN

高级LinCMOSE低噪声斩波稳零运算放大器 Advanced LinCMOSE LOW-NOISE CHOPPER-STABILIZED OPERATIONAL AMPLIFIERS

description

The TLC2654 and TLC2654A are low-noise chopper-stabilized operational amplifiers using

the Advanced LinCMOS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 perfor mance.
