Recommended DAC for use with nRF52832/40

Hi,

I am using the Thingy:52 (that contains the nRF52832) and also have evaluation board of nRF52840.

Does anyone have a recommendation for a DAC for use with one of these boards in terms of simple interface with the micro controller, existing drivers, etc.?

Thanks.

  • Hi,

    I’m still a beginner so take my advice with a grain of salt.

    I would suggest that you first figure out the specifications needed for your project. For example the needed bit resolution, number of output channels, DAC update rate, Voltage output range etc.

    I guess there is a lot of material online on how to choose a correct DAC.

    I only used an AD5721R/AD5761R from Analog Devices so far. It’s a 12-bit DAC with a single output channel. It has a wide range of software-programmable output and works via SPI. Here you can find the driver in the Analog Devices Wiki: https://wiki.analog.com/resources/tools-software/uc-drivers/ad5761r

    Maybe you can find a DAC which uses I2C/TWI, which could be a little bit simpler to use.

    Best regards,

    Nik
