TLC4501系列是美国德州仪器公司生产的新型自稳零运算放大器。该器件采用数字与模拟信号处理技术,上电后300ms内完成自校准过程。只要电路加电,即可自动提取失调电压信息及数字存储,此存储信息可保持,无需连续切断信号来刷新失调电压信息,并且一旦自校准完成,大部分自校准电路自动脱离信号通路并关断,使校准电路对输入信号的影响减到最小。在自校准周期结束后,完全与其它运放一样使用。
TLC4501 series is a new self-zeroing operational amplifier produced by Texas Instruments. The device uses digital and analog signal processing technology, complete the self-calibration process within 300ms after power-up. As long as the circuit is powered up, the offset voltage information and digital storage are automatically extracted, the stored information is maintained without the need to continuously disconnect the signal to refresh the offset voltage information, and once the self-calibration is completed, most of the self-calibration circuits are automatically disconnected from the signal path and turned off , So that the calibration circuit on the input signal to minimize the impact. After the self-calibration period, it is completely used like other op amps.
