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.

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.
