Part Number: DAC9881 Hi team,
My customer found sometimes output voltage is not correct after power-on. I have checked the power up sequence and RSTSEL &USB/BTC setting. No suspect was found. I would like to know if anything else I could take a look…
Part Number: DAC9881 I would like to ask the literature about the feedback resistor.It is unclear. Is RFB an internal resistor?On page 26,Note(1) says RFB can be 1kOhm or 2kOhm depending on the gain.that's handled internally depending on a register setting…
Hello, Any progress on this thread?
As far as solving the issue near the negative rail, depending on how things are actually implemented in your design now, one possibility is to connect the device AGND and DGND pins to a negative voltage, up to -200mV…
