Other Parts Discussed in Thread: ADS1282, , OPA1632
请问在多通道的ADS1282连接中,Switch Output与ADS1282相连接,但是在手册中未提及output引脚如何连接,是否可以如同在单通道的ADS1282连接方式用以连接多个ADS1282

DAC1282的voutp与voutn是差分输出的电压,其共模电压是供电电压中间值-0.1V;
ADS1282的模拟输入端口可以通过寄存器 MUX[2:0]配置差分输入,只要DAC1282的电压输出范围满足ADS1282的电压输入范围即可。如果输出范围不满足输入范围,可以通过全差分运放进行调节,比如 ADS1282EVM中前端电路使用了OPA1632:
