Part Number: ADS8698 Dear engineer, hello!
I used ADS8698 to sample a 1020Hz sine wave output from a DAC. 8698 samples 64 points per waveform cycle, with each point sampled only once. The current problems encountered are as follows: the point obtained…
Other Parts Discussed in Thread: ADS8694 , TIDA-01576 , ISO7763 我打算用ADS8694采集模拟量,然后通过SPI通讯到MCU,但是不知道是否需要和MCU之间完全隔离,用隔离DCDC,SPI用ISO7763隔离?还是电源不需要隔离,GND接在一起,但是这样的话我觉的SPI隔离也不是很有必要了,反正gnd是相通的,spi直接连就行了,我看了TI的几个测试板原理图,TIDA-01576系列,由于测试板没有包括mcu,所以不知道是否需要和muc完全隔离…
