Part Number: ADS7253 Hi TI Team I am using ADS7253IRTER chip for measuring the analog voltage. I want to use internal reference voltage for the ADC. Could you please tell me the steps for configuring the CFR, REFDAC_A, and REFDAC_B registers and readback those registers. Please do tell me the steps for reading the Conversion Data. I am using Microsemi-SmartFusion2 FPGA ( M2S005-VF400I ) and this ADC is connected to FPGA Fabric. I want to develop custom SPI interface code in VHDL/verilog for the configuration and Reading the Conversion Data. I am getting confused with the Timing diagram provided in the datasheet. Could you please suggest the procedure for configuring the ADC and Reading the conversion Data. Configuration: --> Interface Mode : 32-CLK, dual-SDO mode --> Output data format : Straight binary format --> ADC reference voltage source : Use internal reference Below are my values to be written in the registers. CFR Write value = 0x8040 REFDAC_A Write Value = 0x9FF8 (VRef = 2.5V) REFDAC_A Write Value = 0xAFF8 (VRef = 2.5V) CFR Read Control Word = 0x3000 REFDAC_A Read Control Word = 0x1000 REFDAC_A Read Control Word = 0x2000 Conversion Data Read Control Word = 0x8040 Please correct me if my control word is wrong as per above configuration requirement .
