description: |
The ROHM BD7970[0,1,2,3] are 8-bit DACs. The BD79700 has 2 channels,
BD79701 3 channels, BD79702 4 channels and BD79703 has 6 channels.
Datasheets for BD79702 and BD79703 can be found from
https://fscdn.rohm.com/en/products/databook/datasheet/ic/data_converter/dac/bd79702fv-lb_bd79703fv-lb-e.pdf
