DAC with OpAmp
The DAC runs on the MCU 3.3V and the OpAmp runs on external 5V. This board is untested. Outputs are available as an 8 pin IDC connection or terminals. The OpAmp is intended to boost the current available at the DAC output voltage. It may be possible to use this board to generate sound with a speaker. The I2C connection can be made with a PiicoDev adapter and plug in cable. It is possible to send this DAC chip a command to change its address, if you wish to use more than one of them, on the same MCU I2C bus. Note that, !LDAC is permanently grounded and this means that if other !LDAC states are needed that this reassignment will not work; I have have not yet tried it on this board.
This DAC OpAmp Board is available for $7NZD plus postage, as shown directly below.
