    1. Can the EVAL-AD7771FMCZ be used stand-alone without the EVAL-SDP-CH1Z and with the ADR443BRZ instead of the ADR441BRZ to expand the input voltage measuring range?

      Hi ppoli655 , Apologies for getting back just now. You are getting what is expected.R36 should have no effect on the value - only R40 and R38 are considered in the resistor divider if you have SL25 in position A, and if you connected AIN4- to GND. Please refer to the …

      JEstayo , thank you so much for your reply! Thank you for clarifying that point. I thought that in single-end measurements mode - 0V would correspond to , and 2.5V would correspond to . I did not change the ADC data processing code. Why then did it work before and I …

      Hi, JEstayo , To resolve that the input voltage should be the same as the voltage read in DOUTx I disconnected all the sensors from the board. Only DOUTx and power is connected. I connected Vref 2.5V (Vref = 2.5V measured between AD7770_REF+AGND and AD7770_REF+AVSSX) to …

      Hi ppoli655 , I will answer the points you raised separately and please feel free to correct my understanding of your questions. 1. Values are divided by 2, when the potential difference between CH5+ and AGND is measured with a multimeter, the value in the program is 0.25 while SL25 …

      Hi, JEstayo , I've reverted all the changes with resistors so all resistors on all channels have default ratings. I still have values on all channels divided by 2. For example, the voltage between CH5+ and AGND measured with a multimeter is 0.5V, but the value in the program …

      Hi ppoli655 , To achieve a resistive divider through R16, yes you should change SL25 into an open position. Although, please note that this will only work with one channel at a time. Even with SL25 floating, there is still a connection between the middle point highlighted below across all channels …
