1. DESCRIPTION
Diamond-MM-48-AT (DMM-48-AT) is a PC/104 expansion board offering embedded systems designers a full feature set of analog and digital I/O capabilities. It is designed to be used in any PC-compatible embedded computer with a PC/104 (ISA-bus) expansion connector.
DMM-48-AT offers reduced embedded system size and weight, as well as lower cost, by providing more functionality on one board than other data acquisition boards.
Key features include:
Analog Inputs
♦16 single-ended analog inputs
♦16-bit A/D resolution
♦200KHz maximum aggregate A/D sampling rate
♦+/-10V and +/-5V input ranges standard; 0-5V input range optional
♦2048-sample FIFO for reliable high-speed sampling
♦Autocalibrated input circuit
Analog Outputs
♦8 analog outputs
♦12-bit D/A resolution, 0-4.096V output range (1mV per LSB)
♦Autocalibrated output circuit
