The 12-channel PC/104-ADADIO analog I/O board provides high-resolution 16-bit analog input, analog output and digital I/ O. Eight analog input channels are sampled simultaneously. The inputs can be sampled continuously or can be burst-sampled (up to 200,000 samples per channel for an aggregate rate of 1,600,000 samples per second). The inputs are converted and stored in a 32,000-sample FIFO buffer. The four analog output channels are accessed through independent registers, and can be updated either synchronously or asynchronously. Inputs and outputs have a factory-configured range of ±10V, ±5V or ±2.5V. A digital port provides eight bi-directional data lines and two control lines.
