TLV522 是一款 500nA 双路毫微功耗运算放大器,属于 TI 的超值性能毫微功耗运算放大器系列。TLV522 具有 8kHz 增益带宽和 500nA 静态电流,是楼宇自动化和遥感节点中的常见电池供电类 应用 的理想选择。该器件的互补金属氧化物半导体 (CMOS) 输入级可实现超低 IBIAS,从而降低兆欧级反馈电阻拓扑(例如高阻抗光电二极管和充电检测应用)中经常引入的 误差。此外,内置的电磁干扰 (EMI) 保护可降低器件对手机、WiFi、无线电发射器、RFID 阅读器所发出意外射频 (RF) 信号的敏感度。
TLV522 采用 8 引脚 VSSOP (MSOP) 封装,运行温度范围为 –40°C 至 125°C。
