100 dB范围(10nA-1mA)对数转换器

AD8305是一款价格低廉的微型对数转换器，针对确定光纤系统中的光功率应用进行了优化。它采用先进的方式实施经典跨导线性（基于结）技术，可提供多样、易用的宽动态范围。只需采用3 V至12 V单电源供电；也可以选用双电源。低静态电流（典型值5 mA）特性适合电池供电应用。\n\n10 nA至1 mA输入电流IPD施加于INPT引脚，作为一个比例优化的NPN晶体管的集电极电流，该晶体管利用精密对数关系将此电流转换为电压 (VBE)。另一个这种转换器用来处理施加于IREF 引脚的参考电流（IREF）。 这些输入节点经过偏置，略高于地(0.5 V)。对于正极不需要接地的光电二极管应用，一般均可接受。同样 • 针对光纤光电二极管接口进行了优化 \n\n• 50倍电流测量范围\n法则一致性：0.1dB（10nA至1mA） \n\n• 单电源或双电源供电：3 V至12 V\n\n• 完全对数比功能 \n\n• 标称斜率：10 mV/dB（每10倍200 mV） \n\n• 标称截距：1 nA（由外部电阻设置）\n可选的斜率和截距调整功能\n\n• 全面温度稳定性 \n\n• 对于给定电流水平，响应时间极短 \n\n• 16引脚小型芯片级封装\n(LFCSP 3 mm × 3 mm)\n\n• 低功耗：静态电流约为5 mA;
