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

    It's quite possible to play a basic sound file (I think I found 22kHz to be practical). I have done so myself, even managed to get a basic wavetable synth working (doing so required turning off interrupts and very tightly timed code, so maybe not for the faint of heart). The DAC I used was the DAC8411 (www.ti.com.cn/.../dac8411) as I found SPI more practical for sound applications on NRF51 due to the slow I2C interface.
