TLC2252和TLC2254是德州仪器（TI）的双通道和四通道运算放大器。这两款器件均具有轨到轨输出性能，可在单电源或分离电源应用中提高动态范围。 TLC225x系列每通道仅消耗35μA的电源电流。这种微功率操作使其成为电池供电应用的理想选择。与前几代CMOS放大器相比，噪声性能得到了显着改善。如图1所示，TLC225x的噪声水平为19 nV /
Hz ;比竞争对手的微功率解决方案低四倍。
TLC225x放大器具有高输入阻抗和低噪声特性，非常适用于高阻抗源（如压电传感器）的小信号调理。由于微功率耗散水平，这些器件在手持式监测和遥感应用中表现良好。此外，具有单电源或分离电源的轨到轨输出功能使该系列成为与模数转换器（ADC）连接时的绝佳选择。对于精密应用，可提供TLC225xA系列，其最大输入失调电压为850μV。该系列产品的典型特性为5 V和±5 V.
TLC2252 /4还可在标准设计中对TLC27L2 /L4或TS27L2 /L4进行大幅升级。它们提供更高的输出动态范围，更低的噪声电压和更低的输入失调电压。此增强功能集允许它们用于更广泛的应用程序。对于需要更高输出驱动和更宽输入电压范围的应用，请参见TLV2432和TLV2442器件。如果设计需要单个放大器，请参见TLV2211 /21/31系列。这些器件采用SOT-23封装，是单轨到轨运算放大器。它们体积小，功耗低，非常适合高密度，电池供电的设备。
