Hello, For testing purposes I am trying to measure 2.5V with only one ADS131E04 . With RDATA so I can get data perfectly, but with the RDATAC so I can not get correct data. I've attached my electrical schematic, and images of SPI communication. I want to set the ADS131E04 to 4 channels, internal reference 4V, internal clock and 64ksps. SPI configuration: CPOL = 0 CPHA = 1 Baud rate: 8 MHz ADS131E04 configuration: Id = 11010000 Config1 = 10010000 Config2 = 11100000 CONFIG3 = 11100000 FAULT = 00000000 CH1SET = 10000000 CH2SET = 10000000 CH3SET = 10000000 CH4SET = 10000000 FAULT_STATP = 00001111 FAULT_STATN = 00001111 GPIO = 00001111 My command sequence: 1) Reset ADS131E04 (by command) 2) Send SDATAC 3) Configuration ADS131E04 4) START (by command) 5) EnviarRDATAC 6) Check DRDY 7) Receive date 8) STOP (by command) In the measurement results get random values for STAT, CH1, CH2, CH3 and CH4.
