RX23E-B 数字称重传感器微型电路板参考设计
RX23E-B 数字称重传感器微型板参考设计是一款紧凑高效的数字称重传感器设计解决方案,其中采用 RX23E-B 32 位微控制器。 该微控制器集成了高速且高精度的模拟前端 (AFE),无需外置的专用 AFE,从而最大限度地减小了电路板尺寸。 由于称重传感器需要与安装 AFE 和 MCU 的电路板相集成,因此该款电路板必须保证紧凑性。 RX23E-B 将 AFE 和 MCU 集成在单个芯片上,无需外置 AFE,适用于小型化的电路板。 我们为这一参考设计制作了 22mm × 16mm 的微型电路板。
除 RX23E-B 外,此款紧凑型电路板上还包括 RAA788155...
