摘要
ADS1251是一种高精度、宽动态范围的24位△-∑结构模数转换器。介绍了AD S1251的功能特点,并给出了ADS1251芯片在数字化高精度稳流电源中用于采集转换闭环电流反馈信号的硬件电路,与微处理器的接口方法及其时序控制。
The ADS1251 is a precision,wide dynamic range,delta-sigma,Analog-to-Dgital（A/D） converter with 24-bit resolution.The function characteristics of the ADS1251 is briefly introduced.A current feedback signal measuring and convert circuit for high precision current-stabilized power supply is designed by using ADS1251.The circuit design,sequence control flow for the serial interface and the test result are presented.
