Hi peimin Wu, Are you using the IDACs to measure RTDs for example, and therefore use a ratiometric reference? If so, the absolute accuracy of the IDAC might not matter. This is because the current...

Ah- We discovered the issue. The single channel part still defaults to DDR where Channal A is the 1 st cycle and Channel B is the 2 nd cycle. We setup our FPGA to latch on the falling edge of the...

Hi Srinath, The ADC data doesn't go into a register that can be read. The latest conversion data is stored in a buffer, which gets transferred over SPI when using the NULL command. Thanks.

Hi, I can speak on the TPS62916 - Yes the TPS62916 is designed to replace a LDO with low noise and low ripple. 1.2V, 1.8V, 3.3V are all possible. For any questions about AFE58JD28 or LMT8060, I will...

Hi Michael Soldierram, You would just need to use two resistors in series (maybe 3x), and then measure across the top (or middle) resistor. Again, you should perform the calculations to determine if...

thank u for ur answers, if we read the data through null command, each channel consist of 24bits, so for 3 channels I have to send 72bit null data to get back the 72bit digital data in a single spi...

Hi Srinanth, Yes you will need to clock out enough bits to read all the channel conversion data. Please take a look at section 8.5.1.7: 'SPI Communication Frames' of the datasheet. Communication with...

Hi Varsha, What do you mean by write 450? This command (0xC211) would write data 529 to channel D and not update the output. Is that what you are expecting to happen? Best, Katlynne Jones
