The Advme1608B is an isolated A/D converter that provides analog output after a further D/A conversion. It has 16 input channels that can be set at once as 16 single-ended or 8 differential. The board provides 8 analog outputs.
The A/D conversion is started up by the software program and it is executed by switching the channels with a multiplexer. The conversion is started from channel 0 to the channel specified by the software program. When the A/D conversion of the final channel is completed, an interrupt can be issued to the host CPU.
A photo-coupler isolation is provided between analog I/O and digital circuits.
It is possible to update either only one output leaving the other channels untouched (individual update) or all outputs simultaneously (bulk update).
It is possible to perform a batch forced step-down of the output voltage of all channels to 0V at power up or system reset.
