general description the MAX5216PMB1 peripheral module provides the nec - essary hardware to interface the max5216 16-bit dac to any system that utilizes pmod k -compatible expansion ports configurable for spi communication. the ic is a single-channel, low-power, buffered voltage-output dac. the reference voltage for the dac is provided by a 2.5v output version of the max6029 voltage reference (0.15% initial accuracy, 30ppm/c). digital noise is minimized by having spi input buffers powered down after completion of each serial input frame. refer to the max5216 ic data sheet for detailed informa - tion regarding operation of the ic. features s high-accuracy 16-bit dac with on-board precision voltage reference s low gain and offset errors s buffered voltage output directly drives 10k i loads s optional external voltage reference (jumper selectable) s 6-pin pmod-compatible connector (spi) s example software written in c for portability s rohs compliant s proven pcb layout s fully assembled and tested _________________________________________________________________ maxim integrated products 1 MAX5216PMB1 peripheral module 19-6321; rev 0; 5/12 ordering information appears at end of data sheet. pmod is a trademark of digilent inc.
