  • DAC8771: Low Output Amplitude – REFOUT only 1.5V instead of 5V

    Part Number: DAC8771 Tool/software: Hi everyone, we're currently working with a custom PCB that uses the DAC8771, and while basic communication and functionality seem to work, we're encountering a major issue: The output amplitude is far too low. After…

  • DAC8771: DAC Output Voltage & Reference Voltage Not Working

    TI Thinks Resolved
    Part Number: DAC8771 Tool/software: I am currently facing two related problems with the Digital-to-Analog Converter (DAC) implementation: No DAC Output Voltage via SPI Protocol: Despite sending commands via the SPI protocol, I am not observing…

  • DAC8771: DAC8771

    Part Number: DAC8771 Hi, The DAC8771 does not have an enable pin. I tried to limit power consumption of the DAC8771 in a basic application cirquit as shown in the datasheet paragraph 9.2. By resetting the 0x02 and 0x07 registers ( set to 00000001…
