【应用】国产8通道24位ADC SGM58601XSS28G/TR用于DDC，采样速率可达60kSPS

时间： 2022-03-29 来源：世强

技术问答

自动控制箱（DDC）支持多种协议及总线，带通用输入、输出接口，可自由编程、灵活扩展，适用于冷水机组、热泵机组、空气处理机组、送／排风机、精密空调、区域能源站、照明和给排水等应用场景。

下面是系统的原理框图：

在产品设计中需要3通道差分采样的ADC芯片，精度16位，采样速率30kSPS以上，作为无刷电机的电流采样，用来根据电流的变化判断电机是否堵转，防止电机烧坏。同时信号微弱需要ADC芯片内部集成PGA放大功能，噪声要尽量低。在此推荐圣邦微SGMICRO的8通道24位ADC SGM58601XSS28G/TR。

圣邦微SGMICRO的SGM58601XSS28G/TR采样精度可以到24位，超出产品中16位精度的需求，采样速率可以到60kSPS能够保证数据采集的及时性。内部是8通道ADC采集，可以实现4通道差分采集，能够满足产品中3通道差分采集的设计要求。高达23位的无噪声分辨率，最大化提供信噪比，减少干扰信号。内部集成 1 到 64倍增益放大，方便采集微弱信号，省去外部运放，减少PCB布板面积，便于小型化设计。工作温度-40℃到 +125℃，更适合室外更恶劣环境下使用。有SSOP-28 和 TQFN-5×5-28L两种封装，方便用户根据设计需求选择。

【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。
