-16 Single-ended or eight differential inputs -12-bit resolution with five input ranges -Additional gain setting set by resistor -50,000 samples/second (AD12-16) -100,000 samples/second with DMA(AD12-16F) -On-board pacer clock and counter/timers -Two multiplying 12-bit D/A converters -Eight digital I/O lines (4-in and 4-out) -Programmable scan rate -Supports DMA and interrupts -Designed, made, supported, and manufactured in the USA The AD12-16 and AD12-16F are multifunction high-speed analog/digital I/O ISA cards for use in IBM Personal Computers. They are full length cards that can be installed in expansion slots of IBM PC/XT/AT and compatible computers. With this card installed, the computer can be used as a precision data acquisition and control system or as a signal analysis instrument. ANALOG INPUTS The cards accept up to eight differential or 16 single-ended analog input channels. Inputs are protected against over-voltages up to ±35V and, typically, can survive static discharge beyond 4000V. When power is off, the inputs are open-circuited providing fail-safe operation and continue to offer overvoltage protection up to ±20V. The channel input configuration is switch selectable on the card providing a choice between 16 single-ended channels or eight differential channels. In the latter case, common mode rejection ratio is a minimum 86 db and common mode voltage range is ±11V.
