DAC for use with nrf51822

Alison Sinclair

I am using the nrf51822 evaluation board and was planning to use it with sound. There is no DAC included in the board so can anyone suggest a good DAC to use with the board? Thanks

    Hi Alison,

    Unfortunately, it's not straight forward to do this, as we do not have a I2S interface. You can use the ADC (10 bit, 14 kHz max sampling at this resolution) and emulate PWM using a TIMER to output the audio on the receiving radio.

    Best regards Håkon
