Hi ,
Can someone please share the full schematic of the BOOSTXL-ADS7142-Q1?
I found only one page of schematic that too not very clear in the user guide of the evm.

Here you are.BOOSTXL-ADS7142-Q1_A.pdf
Hey Tom , thanks for sharing the document , I suppose this is the latest schematic that you have , referring to the same , in this ADC the i2c address (device address) is configured by a resistive divider according to the resistance values , there's a table given in the datasheet for the same , in the schematic , both the resistances are populated and having the value of 100kohms , for these values there's no such combination given in the table (in the datasheet) , am I missing something here , what i2c address to be used for this ADC ? I am trying to integrate this adc with Sitara am64x processor , the slave address I am using here is 0x18 , but the processor is not acknowledging the ADC , the previous schematic I was referring to had both the resistors as DNP hence did use the 0x18 as address.
I am attaching both the pictures here , could you please clarify this
Hi Shruti,
I only opened the schematic document, not the entire project, so the DNI components are not highlighted in the PDF I provided. You can look at the schematic in the Users Guide and see which resistors are actually populated. For the I2C address, R19 and R28 are both DNP so you should be at address 18h.
