» Functional Description
The A-826PG is a multi-function, 16-bit high resolution Analog and Digital I/O board for the PC/AT compatible computers.
The A-826PG offers 16-channel single-ended or 8-channel differential analog input, plus two channels of analog output with 12-bit resolution.
In addition, the A-826PG has 16-channel digital input, 16-channel digital output and one timer/counter channel.
The A-826PG uses a B.B. ADS 7805 high performance 16-bit A/D converter.
It provides maximum sampling rate up to 100 K samples/s and software programmable gains DMA operation is jumper-selectable for levels 1 or 3. Interrupts are jumper-selectable between 3 and 15.
