description
The TLC2652 and TLC2652A are high-precision chopper-stabilized operational
amplifiers using Texas Instruments Advanced Lin
CMOS process. This process, in conjunction with unique chopper-stabilization circuitry, produces operational
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 variations in temperature, time, common-mode
voltage, and power supply
voltage. In addition, low-frequency noise
voltage is significantly reduced. This high precision, coupled wit...
