本帖最后由 slot867 于 2024-1-26 12:39 编辑

信格勒微电子的芯片产品已通过行业头部大厂导入验证，深受百万终端客户好评。
而且因为 fully compatible. 板子拿来，换个芯片，性能更佳。MCU不用改 c code。

平替TI芯片
SIG1230A 平替 ADS1230 (20-bit）
SIG1232A 平替 ADS1232 (24-bit）

平替ADI芯片
SIG7190 平替 AD7190
SIG7192 平替 AD7192
SIG7193 平替 AD7193

平替Cirrus Logic芯片
SIG5532B 平替 CS5532BS（32-bit）
SIG5534B 平替 CS5534BS（32-bit）
SIG5532A 平替 CS5532AS（24-bit）
SIG5534A 平替 CS5534AS（24-bit）
SIG5530 平替 CS5530 （24-bit）
SIG5530B 平替 CS5530（32-bit）

平替ADI芯片
SIG7792 平替 AD7792
SIG7793 平替 AD7793
SIG7794 平替 AD7794
