Texas Instruments TLV521 350nA 毫微功耗运算放大器
Texas Instruments TLV521 350nA 毫微功耗运算放大器在毫微功耗运算放大器系列中性价比最高。 TLV521 配有一个精心设计的 CMOS 输入级，从而实现非常低的偏置电流（1pA）。 这减少可影响诸如兆欧级电阻、高阻抗光电二极管和充电感测情况等敏感型应用的偏置电流和和 IOS 错误。 此外，内置的 EMI 保护可降低器件对诸如手机和 RFID 阅读器等来源所发出意外射频 (RF) 信号的敏感度。 TLV521 采用 5 引脚 SC70 封装，工作温度范围为 –40°C 至 125°C 。
Additionally, built-in EMI protection reduces sensitivity to unwanted RF signals from sources like mobile phones and RFID readers. The Texas Instruments TLV521 is offered in the 5-pin SC70 package and operates from –40°C to 125°C.
