1.  Introduction 
 
 
1.1  General Description 
 
The OME-A-8111 is a high performance, multifunction (analog and digital I/O) board 
for the PC AT compatible computer with the ISA bus. The OME-A-8111 provides 
programmable gain (1, 2, 4, 8 and 16). The OME-A-8111 contains a 12-bit ADC with up to 8 
single-ended analog inputs. The maximum sample rate of the A/D converter is about 30K 
sample/sec. There is a 12-bit DAC with voltage outputs, 16 channels of TTL-compatible 
digital input, and 16 channels of TTL-compatible digital output.
