【应用】国产圣邦微双通道运算放大器SGM8252AXS8G/TR应用于质谱仪，供电电压范围支持4.5~36V

时间： 2022-10-14 来源：世强

技术问答

质谱仪一款用于分离和检测不同同位素的医疗设备，多用于有机化学、生物学等领域；某客户在设计此类产品主控板上需要一款双通道高精度，轨到轨输出运算放大器，采用12V的供电方式，用于放大电压、电流等模拟信号。本文介绍圣邦微推出的一款双路低噪声高精度运算放大器 SGM8252AXS8G/TR，非常适合此类产品的应用。

以下为质谱仪的部分原理框图：

圣邦微SGM8252AXS8G/TR应用于质谱仪上具有以下优势特点：

1、低电源电流：450μA/放大器（典型），更有效保障产品的续航能力。

2、支持4.5V至36V单电源的高压输入，满足不同应用的供电方式需求。

3、提供低于18μV的低偏移电压和低偏置电流，测量更加精准。

4、低噪声0.1Hz至10Hz和高PSRR达150dB（典型），减少本身器件带来的干扰，提高精度。

【经验】如何提高SGMICRO SGM41285在光模块APD中的工作效率？

用户反馈SGMICRO的DCDC升压变换器SGM41285用在光模块APD时的实测效率和规格效率曲线有差异，存在效率偏低情况，经过排查是因为芯片本身损耗是固定的，包括Rds-on、开关损耗、二极管损耗等，这些是不可避免的；效率测试时，输入电流是1mA量级，建议使用6位半万用表或相近精度的电流表，以排除测量因素的影响。
