  • DAC8563: DAC8563 on different MCU

    Resolved
    Part Number: DAC8563 Other Parts Discussed in Thread: ADS1263 Hello! I tested my DAC8563 with an STM32F466RE and it works great, so I migrate on an STM32F767Zi and it doesn't work! The two programs are quite the same, with only differences in SPI…

  • DAC8563: STM32H7 SPI problems

    Part Number: DAC8563 Hello! I tested my DAC8563 on a STM32H743 but it doesn't work (0V on A & B Channels)... So I tried with an Arduino UNO and it's OK. Times ago I used different STM MCU without problems (F4, F7). This is STM SPI initialization…

    Resolved
    Taha, Today has been a busy day for us in the DAC group with some folks out of office as well, so I apologize for the delay. I will look into your topic more tomorrow, but in the meanwhile it is most helpful to see what is actually happening on the…

  • RE: DAC8563: About the DAC8563 initialization procedure

    I have successfully configured the DAC8563. The output is 0-5V. Can be configured as an upper potential of 2.5V.

  • DAC8563: Datasheet Discrepency

    Resolved
    Part Number: DAC8563 The data sheet on pages 6 and 7 shows different values for the noise density: 250 nV/√Hz@1KHZ (on page 7) and 90 nV/√Hz (on page 6) What is the difference between these two specs and which is the actual number?

  • DAC8563: EMC/EMI/RFI Issues

    Resolved
    Part Number: DAC8563 I have a new sensor design using the DAC8563 chip. The DAC output signals (VoutA, VoutB) are fine until I begin the RFI/EMC immunity tests. When the DUT is subjected to an RF power of 10V/meter, the DAC output voltages shift. During…
