Analog-digital converter card AD8-16

I/O

-16 Single-ended or 8 differential analog inputs -Eight-bit resolution -Over 16,000 conversions per second -Programmable scan rate and voltage ranges -Two 8-bit analog outputs -Three programmable counter/timers -Eight digital inputs -Eight digital outputs +5V output, 1 amp, fused -Designed, made, supported, and manufactured in the USA Model AD8-16 (alternate part number ADA-8) is an economical, multiplexed, eight-bit Analog-to-Digital Converter (A/D) and Counter-Timer card for ISA-bus computers. It accepts up to eight differential or 16 single-ended analog inputs (jumper configured). AD8-16 requires a full-size expansion slot. All connections are made through a standard 50-pin connector. Base I/O address selection is via dip switch. Analog inputs are multiplexed, amplified, held by a sample and hold amplifier, and then digitized by an eight-bit A/D converter. Amplifier gain is selected by software and can differ from channel to channel. Full scale voltage ranges are ±128 mV, ±5V, 0-255mV, and 0-10V. When operating in the bipolar ranges, the digital output is available in 2’s complement or offset binary format. The end-of-conversion signal can be used to interrupt the computer when configured by jumper. You can select from IRQ levels 2-7. The interrupt request is automatically cancelled when the A/D data are read. There are two 8-bit Digital-to-Analog converters on this card. These D/A’s output ranges are -10V to +10V and are intended to drive 10 kilohm or greater load. Maximum output current is 5 mA.
