AMC7832: ADC conversion time

Part Number: AMC7832


When AMC7832 REG 0XC0 bit 0 set to 1, ADC conversion starts. When could we read REG 0X72 BIT 0 to get 1 which means ADC conversion completed? How long does ADC need to finish conversion? Thanks a lot!



  • Hi David,

    The DAVF bit will set when all conversions are complete. The total time for all the conversions to complete depends on the number of channels enabled and the selected conversion rate. The conversion rate is determined by the CONV-RATE field in register 0x10. The time per channel is shown in table 55. For example, if you had only one unipolar channel enabled and your CONV-RATE was set to 'b00, the conversion would take 11.5µs.

    Please let me know if this resolved your issue.
