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 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 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.
This high dc precision and low noise, coupled with the extremely high input impedance of the CMOS input stage,
makes the TLC2654 and TLC2654A ideal choices for a broad range of applications such as low-level,
low-frequency thermocouple amplifiers and strain gauges and wide-bandwidth and subsonic circuits. For
applications requiring even greater dc precision, use the TLC2652 or TLC2652A devices, which have a
chopping frequency of 450 Hz.
