This datasheet introduces the characteristics of the TLC2654 and TLC2654A low-noise chopper-stabilized operational amplifiers
The document describes the TLC2654 and TLC2654A as low-noise, chopper-stabilized operational amplifiers utilizing the Advanced LinCMOS process. These devices are designed for high DC precision with input noise voltage of 0.5 µV peak-to-peak (typical) from 0 to 1 Hz. They feature a high chopping frequency up to 10 kHz and eliminate intermodulation error below 5 kHz, making them suitable for low-level thermocouple amplifiers and strain gauge applications.
