and sequencer

[List, Christopher]

The advantage to the ARP method of using a DAC to create a stepped voltage
is that one (relatively expensive) DAC can be used to drive several
(relatively cheap) channels of quantization - as many as you like!

If you just want to quantize one channel, then yes, an ADC to DAC would be
easier.
