3 說明
THS4541-Q1 是一款低功耗、電壓反饋、完全差分放大器 (FDA)，輸入共模范圍小于負電源軌和軌到軌輸出。其設計用于低功耗數據采集系統，其中高密度對于高性能 ADC 或 DAC 接口設計至關重要。
THS4541-Q1 提供了連接直流耦合地居中源信號所需的負軌輸入。此負電源軌輸入搭配軌到軌輸出，只需使用一個 2.7V 至 5.4V 的電源，即可輕松將單端接地基準雙極信號源與各種逐次逼近寄存器 (SAR)、Δ-Σ 或流水線 ADC 相連接。
THS4541-Q1 在 –40°C 至 +125°C 的額定寬溫度范圍內運行，并且采用具有或不具有可濕性側面的 16 引腳 VQFN 封裝。具有可濕性側面的封裝可簡化組裝后目視檢查，器件型號為 THS4541W-Q1。
