【应用】国产高精度温度传感器SGM450助力10G GPON光模块，典型静态功耗7.5μA

时间： 2022-05-28 来源：世强

技术问答

由于10G光模块成本受限，不少客户采用DDM控制电路、限幅放大器、激光驱动器集成的芯片做主控，这种芯片可读取并校准电源电压，偏置电流，温度，发射功率，接收功率这些参数，但这种方案是没有MCU的，内置的温度传感器在全温度范围内精度不够，因热敏电阻的温度系数为非线性，温度传感器的温度系数呈线性关系，所以需要外挂一颗正温度系数的温度传感器来矫正全温度下的温度精度。

本文介绍一款国产温度传感器圣邦威（SGMICRO）的SGM450，其应用优势如下：

1. SGM450支持宽电压输入2.3~5.5V，符合光模块3.3V供电需求。

2. 精度高：SGM450在0℃~+85℃的温度范围下，传感器精度±0.5℃，在-40℃~+150℃的温度范围下，传感器精度±2℃。

3. 功耗低：典型静态功耗7.5μA，符合光模块低功耗设计要求。

综上，圣邦威的SGM450在10G GPON光模块的应用具有精度高、功耗低、宽温度范围应用的优势。
